摘　　要：为解决试验室条件不足、等轴拉伸试验开展困难等问题,根据单轴压缩与等轴拉伸等价关系,开展橡胶材料单轴拉伸和等效等轴拉伸本构试验,拟合得到最接近试验结果的2阶多项式本构模型参数,对比船用橡胶减振器静变形的有限元计算结果和试验结果发现,该本构模型可较好地描述橡胶减振器的力学性能。In order to overcome the shortages of test facility and the difficulty of axial tensile test,the rubber constitutive test method was proposed based on uniaxial compression which equivalent with axial tensile. According to the experimental results and polynomial constitutive theory,the rubber constitutive model was established. The static deformation of marine absorber was analyzed by finite element method. Comparing the numerical results with the test results showed that the two-order polynomial constitutive model can better describe the deformation of the hyper-elastic rubber absorber.
