Study of Dynamic Stiffness of a Single Air-Spring Model Based on ADAMS/VIEW

Due to the advantages of its non-liner stiffness characteristic,accessible to acquire low vibration frequency,easily averting from a resonance and repressing the resonance amplitude,etc,air-spring is widely used in the bogie of vehicles.ADAMS/VIEW is used to build a non-liner model of air-spring and is conducted.The results show a non-linear relation of dynamic stiffness with its deformation and the dismatch of load extremum with the deformation.
