摘　　要：依据超弹性材料模型,采用工程实用的测试方法,对EPDM(三元乙丙橡胶)材料单轴压缩力学性能进行测试。经过对试验数据的拟合处理,得到超弹性本构模型参数,模型曲线与实测应力应变曲线吻合较好。采用拟合的超弹性本构模型,计算密封设计压缩率下密封圈的接触应力,为产品平面密封的结构设计提供依据。Based on the hyperelastic material model,the mechanical properties of ethylene propylene diene monomer(EPDM)rubber materials under uniaxial compression are tested by using practical engineering test methods.By fitting the test data,the parameters of the hyperelastic constitutive model are obtained,and the model curve is in good agreement with the measured stress-strain curve.The fitted hyperelastic constitutive model is used to calculate the contact stress of the seal under the design compression rate,which provides a basis for the structural design of the product plane seal.
