摘　　要：以某橡胶悬架弹簧为研究对象,基于橡胶材料的超弹性本构方程,综合运用Hypermesh和Abaqus有限元分析软件建立了某橡胶悬架的橡胶弹簧非线性有限元接触模型,论述了橡胶弹簧有限元模型的建立过程,对其非线性刚度特性进行了仿真计算。得到的结果与试验测试数据有较好的一致性,此模型可为橡胶弹簧结构的参数优化提供理论支持,具有一定的工程实用价值。A rubber suspension spring as the research object, according to the rubber material hyperelastic constitutive equation, the rubber spring non-linear finite element contact model of a rubber suspension is established using Hypermesh and Abaqus finite element analysis software, the process of establishing the model is discussed and its nonlinear stiffness characteristics are simulated and calculated. The results obtained are in good agreement with the experimental test data. This model can provide theoretical support for the parameter optimization of the structure of the rubber spring.
