Set the damping for 14, after the damping for 12.
Dampers than ordinary springs have obvious advantages: relatively slow, dynamic force change is not large (generally within 1:1.2), easy to control; disadvantage is that the relative volume of not as small as coil springs, the cost is high, the life of a relatively short.
According to its characteristics and different areas of application, the damper is also known as the support bar, adjuster, pneumatic bar, damper and so on. The dampers are categorized according to their structure and function.
There are several kinds of dampers, such as free-type damper, self-locking damper, traction damper, random stop damper, swivel chair damper, pneumatic bar, damper and so on. At present, the product has a wide range of applications in automotive, aviation, medical equipment, furniture, machinery manufacturing and other fields.
The use of the damper:
The use of air in a closed container compressibility of the spring. Its deformation and load load relationship characteristic line for the curve, can be designed according to the need to count.
The air damper can keep the self-oscillation frequency unchanged under any load, can bear radial and axial loads at the same time, can also transmit a certain amount of torque, by adjusting the internal pressure can be obtained by the different bearing capacity. The structure of the air damper in many forms, there are capsule and membrane, etc., commonly used in vehicle suspension and mechanical equipment vibration prevention system.
