| 摘 要： | 应用INSTRON5544对110甲基乙烯基硅橡胶材料进行了单轴大变形压缩的力学特性测试。本文根据已有的Mooney-Rivilin模型和Yeoh模型的本构关系,采用泰勒级数展开的办法获得了基于小变形的本构关系表达式。利用本文所得本构关系,将实验数据进行了非线性拟合处理,得到了相应的Mooney-Rivilin模型和Yeoh模型的材料参数。拟合所得的名义应力-应变曲线与实测的名义应力-应变曲线吻合较好。利用非线性拟合所得的Mooney-Rivilin模型和Yeoh模型的材料参数,应用ABAQUS软件进行有限元分析计算。通过有限元的分析计算,验证了Mooney-Rivilin模型和Yeoh模型材料参数的正确性与可行性。

| Abstract: | In order to understanding the mechanical properties of 110 methyl vinyl silicone rubber, large deformation uniaxial compression test was carried out by using INSTRON5544. Constitutive relation expressions for small deformation was obtained, based on existing constitutive relations of Mooney-Rivilin model and Yeoh model and by using Taylor series expansion method. Then, corresponding material parameters in Mooney-Rivlin model and Yeoh model were obtained by nonlinear fitting of experimental data obtained from above-mentioned constitutive relation Nominal stress-strain curve from fitting is in agreement with that from experimental data. Using material parameters obtained from nonlinear fitting of Mooney-Rivlin model and Yeoh model and ABAQUS software, finite element analysis was conducted. Calculation results show that the validity and feasibility of material parameters of Mooney-Rivlin model and Yeoh model are verified. |
