摘要

以高速动车组用某型空气弹簧为研究对象，基于非线性、轮胎方程和流固耦合理论，利用ABAQUS有限元分析软件对其进行建模分析。通过相关试验验证了仿真的有效性，然后同时改变附加气室容积和标准高、同时改变附加气室容积和帘线参数，以探究复合参数对垂向刚度的影响。结果表明：附加气室容积越大，随着标准高的增大空气弹簧垂向刚度增加得越快；无附加气室时，帘线层数和帘线间距对垂向刚度影响较大；有附加气室时，帘线层数和帘线间距对其垂向刚度影响较小；在一定范围内，无论附加气室容积多大，帘线角度对垂向刚度的影响都较大。

Abstract

Based on the tire lift equation, nonlinear theory and fluid-solid coupling theory, an air spring system model with an auxiliary chamber was established by using finite element software ABAQUS, and the simulation results were validated by comparing with experiment datum. By changing volume of the air spring with an auxiliary chamber and standard high simultaneously, and altering volume of the auxiliary chamber and cord parameters simultaneously, to explore influence of compositive parameters on the vertical stiffness of air spring. The results showed: volume of the auxiliary chamber was larger, vertical stiffness of the air spring increased more quickly with more standard high; Without auxiliary chamber, cord layer and cord spacing had great influences on the vertical stiffness, while considering auxiliary chamber, cord layer and cord spacing hardly affected the vertical stiffness; within a certain range, no matter how much volume of the auxiliary chamber was, cord angle had great effect on the vertical stiffness.
