What is the vibration isolation principle of air springs?

The vibration isolation principle of air springs is to reduce vibration through the flexibility of compressed gas. When its shell is subjected to external force, the gas will be compressed, and the gas will absorb energy during compression, releasing much less energy than the external force, thus playing a buffering role. Among them, the magnitude of gas compression is related to the magnitude of external force. When the external force changes, the compression of gas will also change to absorb the external force and weaken its power.
