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 spring was established by MARC nonlinear finite element analysis software. The REBAR element was used in the cord-reinforced structure. The stress of the capsule matrix and the cord were calculated and the influence of the cord material parameters on the strength and rigidity of the capsule was analyzed .
