Reduce the noise of the ultimate artifact - air spring:
First of all, from the point of view of the air spring material, the damping area of the air spring is the middle of the rubber airbag portion, the conductivity for vibration is very low, and the frequency from the top cover to the lower end can be reduced to 1 Hz, which can be recognized by the human ear. The minimum increase is about 20HZ, and the effect of air spring damping is not only significant, but also a very large space from the critical value. And the elastic coefficient of the air spring (ie, soft spring and hard spring) can be adjusted by the internal pressure of the pump. Reasonable selection of the air spring can effectively avoid the impact of the impact effect during the use of the air spring.
