The vibration isolation characteristic of a secondary suspension system is a crucial factor influencing the running safety and riding comfort of railway vehicles. This paper put an emphasis on the exploration of the dynamic characteristics of the secondary quasi-zero-stiffness suspension system. Based on the theory of multi-body dynamics, the vertical system model of railway vehicles was established. On this basis, vehicle vibration analysis and calculation program were compiled, and the vibration isolation characteristics of secondary suspension with quasi-zero-stiffness system and traditional linear stiffness system were compared and analyzed.
