摘　　要：通过橡胶试件的拉伸、压缩试验,得出了两种硬度橡胶材料的应力-应变关系;建立两种硬度橡胶波形发生器的有限元模型,分别施加18 kN和28 kN的载荷,得到了采用不同本构模型的最大静态变形量及静态刚度;进行实物试验,并将有限元仿真结果与实物试验结果对比。研究表明:Arruda-Boyce模型相对误差最小,Van der Waals模型相对误差最大。Through stretching and compressing tests of rubber specimens,the stress-strain relationships of two hardness rubber materials were obtained.The finite element models of two hardness rubber waveforrn generators was created,the maximum static deformation and static stiffness of different constitutive models was obtained with loads of 18 kN and 28 kN respectively imposed.Comparison the actual tests and finite element simulation results with physical test results ha been carried out.The conclusion indicates that relative error of Arruda-Boyce model was the minimum while Van der Waals model was the maximum.
