摘要
利用 MARC非线性有限元分析软件建立空气弹簧有限元模型 ,帘线增强结构采用 REBAR单元 ,计算研究了胶囊基体和帘线增强各自的应力情况 ,分析了帘线材料参数对胶囊强度和刚度的影响。
The finite element model of air springs is set up with the application of MARC non linear finite element analysis software. The REBAR unit is applied for the cord reinforcement structure. The stresses of the bellow base and cord reinforcement are calculated and researched. And the effects of the parameters of the cord material on the strength and rigidity of the bellow are analyzed.
