This article has probed into the dynamic characteristic of the air spring with auxiliarychamber. The research results could be reference and guide for further study in the future.
The dynamics equations of air spring system with auxiliarychamber were established, and the complex stiffness model of the system was deduced according to the equations being linearly processed.
The oxide-coated zirconium of the chambers at the piston and cylinder head, the design of air gap on the auxiliarychamber are applied to lower heat rejection.
