摘　　要：空气弹簧是现代轨道交通车辆的主要减振元件,能有效改善轨道车辆的动力学性能,提高乘坐的舒适性和车辆的运行稳定性。文章利用非线性有限元软件ABAQUS对空气弹簧的垂向刚度与横向刚度进行模拟分析,通过考虑空气弹簧的非线性性质、结构参数等影响空气弹簧刚度的因数,对基于各影响因数下空气弹簧刚度特性进行比较分析。Airspring is the main damping components of the modern rail transit vehicles,which can effectively improve the rail vehicle dynamic performance,raising the ride comfort ride comfort and stability of vehicles.Using the nonlinear finite element software ABAQUS to simulate the vertical stiffness and lateral stiffness of air spring,by considering the factor of affecting air spring stiffness including nonlinear nature and structure parameter,simultaneously comparing the stiffness of air spring based on the different influence factors.
