摘要：
As secondary suspending system, suspending parameters and simplified model of air spring has important effect on vehicle dynamical analysis. Aiming at air spring system of low-speed maglev train, the dynamical model of air spring with auxiliary chamber was established. Based on amplitude-versus-frequency characteristics analysis of levitation system and air spring system, the air spring system was reduced to a second order oscillation system, the equivalent stiffness and damping of air spring system were obtained. The research results provided a theory basis for optimal design of air spring and vehicle dynamical analysis.
