Wooden models, crystal models, ABS resin models, metal models and so on.
Models can take a variety of different forms, there is no uniform principle of classification. According to the manifestation of the model can be divided into physical models, mathematical models, structural models and simulation models. Also known as solid models, can also be divided into physical models and analogical models.
①Physical model: according to the theory of similarity manufactured according to the original system proportionally reduced (can also be enlarged or the same size as the original system) of the physical object, such as wind tunnel experiments in the aircraft model, the hydraulic system experimental model, architectural model, ship model and so on.
② analogical model: in different areas of physics (mechanics, electricity, thermodynamics, fluid dynamics, etc.) of the system of their respective variables are sometimes subject to the same law, according to this *** with the law can be made in a completely different physical meaning of the analogical and analogical model. For example, under certain conditions, the pressure response of a pneumatic system consisting of a throttle valve and a gas capacitor has a similar law to the output voltage characteristics of a circuit consisting of a resistor and a capacitor, so that it is possible to simulate a pneumatic system with a circuit that is relatively easy to experiment with. Definition: Industrial model, commonly known as hand plate, first board model and rapid prototyping, the main production methods are CNC machining, laser rapid prototyping and silicone mold small batch production. Industrial models are widely used in the research and development stage of industrial new product design, processing and design consistent with the physical model in the shortest possible time. Designers can confirm the appearance of the product and test the function, so as to improve the design scheme, reduce the development cost, shorten the development cycle, and quickly obtain the customer's approval of the purpose.
Applications: Digital products (cell phones, telephones, USB, headphones, cameras). Home appliances and medical products (TV sets, computers, air conditioners, vacuum cleaners, printers, copiers, washing machines, kettles, massagers, ultrasound machines). 3. Auto parts (car dashboard, door, car air conditioning, car DVD lights, reverse plate, bumper).
Today's industrial models are not as simple as handboards, which have been transformed into large-scale mechanical and engineering models from digital products, home medical products and auto parts. It is even larger than architectural models, and the difficulty factor of the process is further increased. A model expressed through a program running on a digital, analog or hybrid computer. Using an appropriate simulation language or program, physical, mathematical and structural models can generally be transformed into simulation models. Regarding the effects of different control strategies or design variables on the system, or the possible effects of some perturbation of the system, it is preferable to experiment on the system itself, but this is not always feasible. There are various reasons for this, e.g., the experimentation may be expensive; the system may be unstable and the experimentation may disturb the equilibrium of the system and cause danger; the time constant of the system is large and the experimentation takes a long time; the system to be designed does not yet exist, etc. In such cases, simulation modeling of the system is effective. For example, the methanation process of organisms is an adiabatic fermentation process that produces methane due to decomposition by bacteria. Based on the knowledge of biochemistry it is possible to build a simulation model of the process, to seek the optimal steady state value of the process by computer and to study various starting methods. These studies are almost impossible to perform on the system itself, because it is technically difficult to keep the process in steady state and the start-up of the biomethanation reaction is slow and takes several weeks. However, if a (simulation) model is used to simulate the process on a computer, the start-up process of the methanation reaction takes only a few minutes.
Digital models, also known as digital sand table, multimedia sand table, digital sand table system, etc., it is a three-dimensional approach to modeling, simulation of a three-dimensional buildings, scenes, effects, can be in the digital scene at will to roam, gallop, fly, zoom, from the whole to the local and then from the local to the whole, without limitations. Three-dimensional digital technology to build a three-dimensional digital city, virtual model room, traffic bridge simulation, three-dimensional visualization of landscape planning, three-dimensional simulation of ancient architecture, mechanical industrial equipment simulation demonstration with the help of pc machines, display systems play a role in displaying, explaining, commanding, explaining and so on. Multimedia sand table is the use of projection equipment combined with physical planning model, through the precise alignment, the production of dynamic plane animation, and projected onto the physical sand table, thus producing dynamic changes in the new physical model of the form of expression.
Digital model through sound, light, electricity, images, three-dimensional animation and computer program control technology and physical model integration, you can fully reflect the characteristics of the display content, to achieve a fantastic, changing dynamic visual effects. For visitors is a new experience, and can produce a strong **** Ming. Digital model is the largest and earliest model design and production company by the domestic Shenzhen Saino model put forward a new concept. Its self-developed digital simulation technology has been awarded a national patent, and in its Shaoguan Planning Office, Shaoguan city overall planning project on the specific embodiment. Digital model of this new term will be in the near future to replace the traditional architectural models, jumping into the display content of another new highlights. Digital model beyond the monotonous entity model sand table display, in the traditional sand table on the basis of increased multimedia automation program, fully expresses the characteristics of the district, the four seasons change and other rich dynamic visual effects. It is a brand-new experience for customers, which can produce a strong sense of visual shock. Customers can also choose to watch the corresponding display content through the touch screen, simple and convenient, greatly improving the interactive effect of the entire display.
