摘　　要：利用SIMPACK软件建立某高速客车动力学模型,重点研究了一系垂向减振器特性对高速客车运行稳定性和平稳性的影响,不仅较为精确地考虑了减振器的刚度和阻尼大小,而且还考虑了减振器的接头安装刚度、阻尼对称性和卸荷特性等因素。分析结果表明,在适度的范围内选取一系垂向减振器各参数,对高速客车运行稳定性影响很小,对运行平稳性有一定的影响。The dynamics model for a certain type of high speed passenger cars is established with the SIMPACK software.The effect of the features of primary vertical dampers on the running stability and ride comfort of high speed passenger cars is mainly researched.Not only the stiffness and damping of the dampers are considered fairly accurately,but also the end connection stiffness,damping symmetry and unloading characteristics of the dampers are considered.The analysis result shows that selecting the parameters of the primary vertical dampers within an appropriate range has a very little effect on the operation stability of high speed passenger cars,but has certain effect on the ride comfort.
