Analysis of Dynamic Characteristic Parameter of Air Spring

Based on the theories of thermodynamics and hydrodynamics, a physical model for air springs is established, its uniform mathematical expression is deduced, and the method of determining air spring parameters is put forward. And the factors affecting the dynamics of air springs are analyzed. The results showthatshape ofthe air cell, properties ofthe material, volume ofthe appended gas chamber and diameter of the throttle hole are main factors affecting the dynamics of air springs.
