The vibration of the snow shovel static and dynamic strength analysis and the latest technology of snow-removing machinery
Wang Xishan
I focus on research and development of snow-removing equipment in 2000, is the "vibration" of the snow shovel inventor. Research and design of snow removal machinery and equipment first to ensure that the use of snow and ice removal machinery and equipment and the realization of the performance, now on the Jilin University Professor Liu Yibin, Wang Xiushan, Ma Wuxing, Lv Jingzhong and other professors of the "vibration of the snow shovel static and dynamic strength analysis," the dialysis, and snow removal machinery and equipment in the design of the structure that must be briefly explained, I try to achieve the language of the plain language and easy to understand, has been to guide the research and development of machinery and equipment to remove the snow in the field of the Thinking not into the wrong area, to promote the development of products.
Jilin University, Liu Yibin, Wang Xiushan, Ma Wuxing, Lv Jingzhong of the vibration of the snow shovel static and dynamic strength analysis (referred to as: "analysis"), from the spring of 2011, Jilin University by the city of Baishan City, an enterprise, for the enterprise to improve the vibration of the snow shovel on the basis of the production process, the analysis and the actual difference is very far. The Analysis mentions "vibration", "ice and snow crushing", "automatic obstacle-crossing" in the abstract, and "snow shovels can impact and crush compacted snow and ice and automatically cross the obstacles" in the snapshot of the main text. Compacted snow and ice can be broken up and removed by the impact of the shovel" is unrealistic. The analysis of the concept and thesis is wrong, its content certainly deviates from the actual, I analyze this, in order to play a correct role in guiding the research and development of snow and ice machinery, to enrich the theoretical and practical basis of research and development, and better service to the people and society.
First, in addition to the current status of the performance of snow and ice machinery and equipment Currently at home and abroad, there is no a real sense of being able to get rid of the ice on the road machinery and equipment, one of the reasons is that in addition to the snow machinery relative to other mechanical development is relatively late, the countries do not have the formation of ice must be cleared and other special requirements of the road surface. Reason two is the formation of ice is a typical material three state, that is, from the liquid water in the cold after the formation of a solid state on the road, so the ice and road affinity is very strong, ice and asphalt hardness and basically in line with the hardness of the two objects in line with the hardness of the two and does not damage the road, is difficult to achieve the mechanical force, I'm on the effective removal of ice on the road surface research and development and breakthroughs, and soon the product will be launched.
The world's countries on the road snow removal are based on different national conditions have different snow removal machinery and equipment, and have the actual effect of snow removal. China's winter snow on the road surface has a certain specificity, crushed compacted snow accounted for more than 70%, crushed compacted snow on the road surface adhesion is very strong and has a certain degree of affinity, there is no stable performance at home and abroad in addition to the compaction of the snow machinery and equipment. China's urban pavement and highway pavement are different protruding objects, which forces a variety of snow removal machinery and equipment must have a good avoidance, in this regard, the performance of all the snow removal machinery is not ideal, is to avoid the performance of snow removal machinery and equipment to remove the effect of snow can not meet the requirements. Jilin Jieying R & D production of various snow removal machinery and equipment through the market verification, in addition to compacted snow, ice and snow mixtures (snow did not fully formed ice), the effect of natural snow is very good, when encountered in the road surface protruding objects can be over, over the servo reset to continue operations, this aspect of the industry is worthy of study and reference and worthy of reorganization to expand the production of services to the community.
Two, dialysis of Jilin University, Liu Yibin, Wang Xiushan, Ma Wuxing, Lv Jingzhong of the vibration of the snow shovel static and dynamic strength analysis (referred to as: "analysis") of the concept of the "analysis" in the summary of the "vibration", "snow and ice vibration broken", In its summary, the Analysis refers to "vibration", "ice and snow vibration and shredding", and "automatic obstacle-crossing", which are indeed impractical, and de-icing cannot be realized at all.
1, "vibration" dialysis de-pressurization of snow machinery and equipment with vibration performance does have a certain effect but by no means "vibration", vibration and "vibration" is not a concept. Vibration and "vibration" is not a concept. Vibration refers to the mechanical equipment as a whole active vibration, snow removal shovel operation is part of the implementation of the structure of the shovel blade, shovel blade has a vibration frequency of more than 5,000 times/min above the function and the road surface to form a certain angle, in addition to the snow and ice can play a very good role in my research and development after many years has been completed this vibration shovel and will soon come out, this vibration shovel can be the ice and snow to remove the vibration of the broken. "Vibration" is a form of active reciprocating motion of mechanical equipment, "vibration" on a variety of mechanical equipment to have certain limitations, "vibration" frequency can not be too high or mechanical equipment Produce *** vibration so that the equipment can not operate. In the snow removal machinery and equipment, if the shovel blade and the road surface to form the angle suitable for snow removal, "vibration" connecting part of the structure of the mass of 300kg, "vibration" reciprocating 8mm, frequency 600 times/min, snow removal machinery as a whole does not produce *** vibration in the Relative equilibrium value of the case, according to this set of data, the shovel blade unidirectional "vibration" line speed of 4800mm/min, if the overall snow removal machinery and equipment operating speed is set at 50,000 mm/min (3km/h), then the shovel blade does not realize the reciprocating "vibration ", that is, "vibration" in the snow removal operation is not realized "ice and snow vibration broken" performance, so the body of the snapshot mentioned in the "snow shovel can be compacted ice and snow impact broken and be Therefore, the snapshot in the text that says "snow plows can impact compacted snow and ice and remove it" is not realistic. The statement itself is a misconception of performance, and the content of its Analysis is certainly off the mark.
2, "automatic obstacle" description is not clear snow removal shovel snow removal operation over the road protruding objects performance is very critical, this performance determines the snow removal shovel can carry out snow removal operations. Jilin University copied the structure of the snow removal shovel produced by the Jilin Baishan enterprise, and applied for a utility model patent (201220271647.4), the main structure and others as early as 2010 applied for a national patent (201020162151.4) is exactly the same, the structure of the snow removal shovel in the slow-speed snow removal operations can be automatically over the protruding objects on the road surface, can not be automatically reset after the overpass, requiring the operator servo reset, the structure of the snow removal shovel in the slow-speed snow removal operations can automatically over the protruding objects on the road, the operator servo reset. After crossing, it can't be reset automatically, but needs servo reset by the operator, and the description of "automatic barrier-crossing" is very easy to mislead the industry insiders and users about the real understanding of the performance. I designed the full-automatic over the barrier reset in addition to compaction snow shovel will soon face the market.
Three, snow removal machinery and equipment in the structural design of the basic requirements
1, snow removal machinery status quo China's winter snowfall in the city is basically snowfall at the same time the vehicle on the road uninterruptedly, so that the city roads are mainly compacted snow, in addition to Jilin, Jieying production of snow shovels, there is no stable performance in addition to the compaction of solid snow machinery and equipment. Because the shovel blade and the road surface angle of the design is unreasonable, the design of the lack of obstacles, resulting in a variety of snow shovels in the operation of the basic downward pressure restrictions, so that snow shovels can not reach the performance of snow removal. The whole machine snow removal walking machinery is because of the consumption of parts consumed too quickly, the structural design of the lack of factors leading to unstable performance. As the market demand for snow removal machinery is very large, there is a certain profit margin, the general means of manufacturing can be realized and other factors, prompted by a certain condition of the unit or individual with an idea of production and sales, so that the market for snow removal machinery and equipment, a mixed bag of fish and beads.
2, snow removal machinery and equipment in the structural design of the basic requirements of the structural design and shovel blade and road design directly affect the performance of snow removal machinery. According to many years of testing and research on various snow, urban roads to remove snow shovel for the best choice, according to road conditions and snow conditions of different shovel blade and road surface angle 30 ° -50 ° (the formation of the acute angle), shovel blade over the obstacle structure of the latter tumbling type for the best design. Compacted snow hardness and general hardened road hardness difference is very big, according to the shovel artificial snow mechanical analysis, snow shovel blade must have three points of force, so that the shovel blade like artificial snow removal to compacted snow from the road surface, but the shovel blade material requirements are very high, through the experiments of its hardness should be in the HRC52-58 and have a certain degree of impact resistance, snow shovel snow removal operations
Road or highway snow removal speed is relatively high, in addition to the net rate than the city road to be relatively low, so the shovel blade and the road surface angle is suitable for 75 ° - 80 ° (the formation of acute angle), snow removal operation speed is suitable for 15Km / h - 60Km / h. Because of the operating environment of the snow removal equipment is relatively harsh, in the design of the equipment to make the snow removal operation speed is appropriate. Because the operating environment of the snow removal equipment is relatively harsh, in the design of the equipment as a whole can withstand all aspects of the force, the choice of materials to make the equipment have a certain degree of elastic deformation after the force. Jilin Jieying production of urban road snow shovel and highway snow shovel is a more successful design, the relevant structure can be referred to, but due to intellectual property rights can not be imitated.
3, snow removal brush snow removal machinery and equipment in the brush is an indispensable device, the biggest advantage of the brush is to remove the high rate of purification, but is limited to removing a relatively small amount of snowfall of natural snow. At present, due to the roller brush in the structural design of the lack of, in the operation of the roller brush on the ground pressure is not equal, resulting in the number of revolutions or high or low or even stop, the wear and tear of the brush filament is also very large or broken from the root, which is due to the unevenness of the road surface and the changes in the tire pressure of the vehicle trailer, and therefore, the roller brush in the structural design of the elimination of or to compensate for the adverse effects brought about by these factors.
City roads on both sides are sidewalks, viaducts are also many, roller brush or other snow removal machinery and equipment to remove the snow can not be thrown to both sides or stacked, not to repeat the operation, so snow removal machinery and equipment to have to remove the snow thrown directly to the performance of the transport vehicle.
Dialysis of Wang Xiushan's "multi-functional vibration snow shovel research"
and the latest snow removal machinery technology
Wang Xishan
I focused on research and development of snow removal equipment in 2000, is the "vibration" snow shovel inventor. Research and design of snow removal machinery and equipment first to ensure that the use of snow and ice removal machinery and equipment and the realization of the performance of the Jilin University Wang Xiushan's "multi-functional vibration snow shovel research" analysis, and snow removal machinery and equipment in the future design of the structure must have to be briefly explained, I try to achieve the language is easy to understand, has guided the research and development of machinery and equipment in the field of snow removal of the thinking is not into the wrong area, to promote the development of the product.
Wang Xiushan of Jilin University, "multi-functional vibration snow shovel research" (referred to as: "thesis") of the paper, from the spring of 2011 by the Jilin University of Baishan City, an enterprise entrusted to improve the vibration of snow shovels for the enterprise on the basis of the production process, the "thesis" and the actual difference is very far. The theory of "lifting effect", "vibration" and "height of obstacle" mentioned in the abstract of the thesis is very different from the actual design theory, which is very one-sided. Mechanical equipment, only the latest design is not the best design, I in line with the technology is responsible for the product is responsible for the community is responsible for the attitude to analyze, in order to research and development of snow and ice machinery to play a role in guiding the correct, enrich the theoretical and practical basis of research and development, to better serve the people and society, I also put the latest R & D and design of the product technology and performance to be introduced.
First, in addition to the current status of the performance of snow and ice machinery and equipment Currently at home and abroad, there is no one true sense of the road to get rid of the ice on the machinery and equipment, one of the reasons is that in addition to the snow machinery relative to other mechanical development is relatively late, the countries do not have the formation of ice must be cleared of the road surface and other special requirements. Reason two is the formation of ice is a typical material three state, that is, from the liquid water in the cold after the formation of a solid state on the road, so the ice and road affinity is very strong, ice and asphalt hardness and basically in line with the hardness of the two objects in line with the hardness of the two and does not damage the road, is difficult to achieve the mechanical force, I'm on the effective removal of ice on the road surface research and development and breakthroughs, and soon the product will be launched.
The world's countries on the road snow removal are based on different national conditions have different snow removal machinery and equipment, and have the actual effect of snow removal. China's winter snow on the road surface has a certain specificity, crushed compacted snow accounted for more than 70%, crushed compacted snow on the road surface adhesion is very strong and has a certain degree of affinity, there is no stable performance at home and abroad in addition to the compaction of the snow machinery and equipment. China's urban pavement and highway pavement are different protruding objects, which forces a variety of snow removal machinery and equipment must have a good avoidance, in this regard, the performance of all the snow removal machinery is not ideal, is to avoid the performance of snow removal machinery and equipment to remove the effect of snow can not meet the requirements. Jilin Jieying R & D and production of a variety of snow removal machinery and equipment through the market verification, in addition to compacted snow, ice and snow mixtures (snow did not fully formed ice), the effect of natural snow is very good, when encountered in the road surface protruding objects can be over, over the servo reset to continue operations, this aspect of the industry is worthy of study and reference and worthy of reorganization of the expansion of the production of services to the community.
Two, dialysis of Jilin University Wang Xiushan "multifunctional vibration snow shovel research" (referred to as: "thesis") the concept of "thesis" mentioned in the summary of the "lifting effect", "vibration", "height" and other theories, with the actual height of the obstacle. In the abstract of the Thesis, the theories of "lifting effect", "vibration", "height of obstacle crossing", etc. are very different from the actual design concepts, and have a great deal of one-sidedness.
1, "vibration" dialysis In addition to compaction snow mechanical equipment with vibration performance does have a certain effect but never "vibration", vibration and "vibration" is not a concept. Vibration and "vibration" is not a concept. Remove compacted snow shovel mainly lies in the shovel blade and road surface angle design and the design of the barrier structure. Vibration refers to the mechanical equipment as a whole active vibration, snow shovel operation is part of the implementation of the structural part of the shovel blade, shovel blade has a vibration frequency of more than 5000 times/min above the function and the road surface to form a certain angle, in addition to the snow and ice can play a very good role (I after years of research and development has been completed this kind of vibration shovel and will soon come out, this kind of vibration shovel can be broken to remove the snow and ice vibration). "Vibration" is a form of active reciprocating motion of mechanical equipment, "vibration" on a variety of mechanical equipment to have certain limitations, "vibration" frequency can not be too high or mechanical equipment Produce *** vibration so that the equipment can not operate. In the snow removal machinery and equipment, if the shovel blade and the road surface to form the angle suitable for snow removal, "vibration" connecting part of the structure of the mass of 300kg, "vibration" reciprocating 8mm, frequency 600 times/min, snow removal machinery as a whole does not produce *** vibration in the Relative equilibrium value of the case, according to this set of data, the shovel blade unidirectional "vibration" line speed of 4800mm/min, if the overall snow removal machinery and equipment operating speed is set at 50,000 mm/min (3km/h), then the shovel blade does not realize the reciprocating "vibration ", that is, "vibration" in the snow removal operations will not realize the "ice and snow vibration broken" performance, so the summary mentioned in the "through the vibration shovel breaking ice and snow removal test: for different Ice and snow density, vibrating shovel removal rate can reach 95%, to meet the requirements of modern snow removal" is fiction and imagination.
2, "over the barrier test" description one-sided snow removal shovel snow removal operation over the road surface protruding objects performance is very critical, this performance determines whether the snow removal shovel is able to carry out snow removal operations. Jilin University copied the structure of the snow removal shovel produced by the Jilin Baishan enterprise, and applied for a utility model patent (201220271647.4) (Wang Xiushan is one of the participants), the main structure and others as early as 2010 applied for a national patent (201020162151.4) is exactly the same, the shovel blade overruns the obstacle height depends on the dimensions of the other relevant structural components, the overrun height is the same, the shovel blade overruns the obstacle height is the same. to the terminal data of the series data chain. With the shovel blade constantly in the operation of the wear and tear, its overrun height also changed, snow removal operations at any time at any time overrun phenomenon, so the "thesis" elaborated "through the shovel blade overrun test verified that the snow shovel can overrun the obstacles of the maximum height of 140mm" is very one-sided. Can make the shovel blade to achieve the effect of overrun a variety of mechanical structures, I designed a variety of shovel blade roll back overrun, fully automatic overrun reset, no vibration or vibration in addition to the compaction of the snow shovel as well as the highway fast snow overrun snow shovels will soon be facing the market.
3, "thesis" in the thesis dialysis snow shovel to strip the road surface after snow shovel will be with the snow shovel main plate arc, the operation of the walking direction of the angular slope to the side of the sliding emissions. Sliding discharge speed and height and shovel blade material, shovel blade and the ground angle, the walking direction of the angle, the size of the main board arc, the snow viscosity value, the size of the snow particles (blocks), the density of the snow particles (blocks), the operating speed fast or slow, the weather temperature is high or low, etc., this type of machinery is the purpose of the operation, the operating effect, the operating cost of the ultimate goal of the design of the non-standard machinery, so the "thesis" of the The data of this form of structure snow removal shovel is not in line with the reality.
The paper's statement that "snow plows throw well" is one-sided. The effect should be determined by the fact that sidewalks, buildings, etc., are not affected, much less the snow being thrown or piled up on the sides of viaducts on the city's highways.
Three, snow removal machinery and equipment in the structural design of the basic requirements
1, snow removal machinery status quo China's winter snowfall in the city is basically a snowfall at the same time the vehicle on the road uninterruptedly, so that the city roads are mainly compacted snow, in addition to Jilin JieYing production of non-vibrating snow shovels, there is no stable performance in addition to the compaction of the snow machinery and equipment. Because the shovel blade and the road surface angle of the design is unreasonable, the design of the lack of obstacles, resulting in a variety of snow shovels in the operation of the basic downward pressure is limited, so that snow shovels can not reach the performance of snow removal. The whole machine snow removal walking machinery is because of the consumption of parts consumed too quickly, the structural design of the lack of factors such as performance instability. As the market demand for snow removal machinery is very large, there is a certain profit margin, the general means of manufacturing can be realized and other factors, prompted by a certain condition of the unit or individual with an idea of production and sales, so that the market for snow removal machinery and equipment, a mixed bag of fish and beads.
2, snow removal machinery and equipment in the structural design of the basic requirements of the structural design and shovel blade and road design directly affect the performance of snow removal machinery. According to many years of testing and research on various snow, urban roads to remove snow shovel for the best choice, according to road conditions and snow conditions of different shovel blade and road surface angle 30 ° -50 ° (the formation of the acute angle), shovel blade over the obstacle structure of the latter tumbling type for the best design. Compacted snow hardness and general hardened road hardness difference is very big, according to the shovel artificial snow mechanical analysis, snow shovel blade must have three points of force, so that the shovel blade like artificial snow removal to compacted snow from the road surface, but the shovel blade material requirements are very high, through the experiments of its hardness should be in the HRC52-58 and have a certain degree of impact resistance, snow shovel snow removal operations
Road or highway snow removal speed is relatively high, in addition to the net rate than the city roads to be relatively low, so the shovel blade and the road surface angle is suitable for 75 ° - 80 ° (the formation of the acute angle), snow removal speed is suitable for 15Km / h - 60Km / h. And in the snow removal equipment for the operation of the environment is relatively The operating environment of the snow removal equipment is relatively harsh, in the design of the equipment as a whole can withstand all aspects of the force, the choice of materials to make the equipment have a certain degree of elasticity and deformation after the force. Jilin Jieying production of urban road snow shovel and highway snow shovel is more successful design, the relevant structure can be referred to, but because of intellectual property rights can not be imitated.
3, snow removal brush snow removal machinery and equipment in the brush is an indispensable device, the biggest advantage of the brush is to remove the high rate of purification, but is limited to removing a relatively small amount of snowfall of natural snow. At present, due to the roller brush in the structural design of the lack of, in the operation of the roller brush on the ground pressure is not equal, resulting in the number of revolutions or high or low or even stop, the wear and tear of the brush filament is also very large or broken from the root, which is due to the unevenness of the road surface and the changes in the tire pressure of the vehicle trailer, and therefore, the roller brush in the structural design of the elimination of or to compensate for the adverse effects brought about by these factors.
City roads on both sides are sidewalks, viaducts are also many, roller brush or other snow removal machinery and equipment to remove the snow can not be thrown to both sides or stacked, not to repeat the operation, so snow removal machinery and equipment to have to remove the snow thrown directly to the performance of the transport vehicle.
Four, my latest design of a variety of snow removal machinery performance snow removal machinery and equipment applications, so that the winter snow clearing has been fast, but due to the use of snow removal equipment is particularly harsh environment, the use of the crowd can not get good business technology training, prompting this field of products to have a good use of the performance and stability of performance. Snow removal machinery and equipment development, is a very complex and difficult technical project, after many years of research and production experiments, a variety of road snow removal machinery has been successfully developed and launched and has been well received by the market, the launch of these products and technologies mark China's road snow removal machinery field across a new period of development, is a qualitative leap, but also marks our country in the field of snow removal machinery, pavement cleaning equipment in the field of leading the international level. International level.
