摘要

动车组空气弹簧的力学特性往往具有较强的非线性与耦合性,涉及到几何非线性、材料非线性和接触非线性等问题,给计算分析带来了较大的困难。为了准确获得动车组空气弹簧在工作过程中的垂向静力学特性,本文使用有限元软件ABAQUS建立了动车组空气弹簧非线性力学仿真模型。基于该模型对空气弹簧垂向静态刚度试验进行模拟,分析了初始内压、振幅、帘线角度和帘线间距对空气弹簧垂向静刚度的影响。
        The mechanical characteristics of air spring of EMU often have strong nonlinearity and coupling, which involves geometric non-linearity, material non-linearity and contact non-linearity, and brings great difficulties to calculation and analysis. In order to accurately obtain the vertical static characteristics of the air spring of EMU in the working process,the mechanical simulation model of the air spring of EMU is established by using the non-linear finite element software ABAQUS. Based on this model, the vertical static rigidity test of air spring is simulated, and the effects of initial internal pressure, amplitude, cord angle and cord spacing on the vertical static rigidity of air spring are analyzed.
