How do we solve vibration and noise problems in mechanical
equipment? The answer is to use air springs.
The air spring is a spring made by filling a retractable airtight
container with compressed air and utilizing the elastic force of
the air. Its working principle is to fill the closed pressure
cylinder with inert gas or oil-gas mixture, so that the pressure in
the cavity is several times or dozens of times higher than the
atmospheric pressure, and the pressure generated by the
cross-sectional area of the piston rod is smaller than that of the
piston. It is not easy to realize the movement of the piston rod.
Due to the difference in principle, gas springs have significant
advantages compared with ordinary springs: the speed is relatively
slow, the power change is small (generally within 1:1.2), and the
control is convenient.
The air spring has excellent vibration isolation and noise
reduction functions, and the air spring equipment has excellent
nonlinear rigidity, which can effectively limit the amplitude,
avoid resonance and prevent impact. The air spring can absorb
high-frequency vibration and has excellent sound insulation
performance. In addition, increasing the overall volume of the air
spring can also reduce the natural frequency of the vibration
isolation system. This is the unique advantage of air springs.
