摘要:
基于微孔橡胶材料的单轴拉伸与压缩实验，运用超弹性本构模型拟合实验数据，采用精度评价方法对拟合效果进行评估，分析了适用于微孔橡胶材料的本构模型对应变区间的影响程度，并用拟合本构参数对微孔橡胶垫静刚度进行有限元模型的有效性验证。结果表明，材料在实验中存在较强的Mullins效应，5参数本构模型中Mooney-Rivlin 5拟合效果较好，有限元模型对静刚度预测值与试验值的相对误差为9.85%。
Abstract:
Based on the uniaxial tensile and compression tests of the microporous rubber material, the superelastic constitutive model was used to fit the test data, and the accuracy evaluation method was used to assess the fitting effect. The influence of the constitutive model on the strain intervals that was applicable to the microporous rubber material was analyzed. The effectiveness of the finite element model was verified for the static stiffness of the microporous rubber material using the fitted constitutive parameters. The results showed that the material had a strong Mullins effect in the test and Mooney-Rivlin 5 was the best fit. The relative error between the predicted value and the test value of the static stiffness of the finite element model was 9.85%.
