摘要: 根据橡胶材料不可压缩性假设,利用超弹性理论推导出了单轴应力状态下橡胶ArrudaBoyce超弹性模型应力应变关系。结合橡胶抗冲瓦试件单轴拉压实验数据,利用多元线性回归法拟合得到ArrudaBoyce超弹性本构模型参数μ和λm。同时利用Modelcenter集成Abaqus探讨了黏超弹性参数对抗冲瓦结构抗冲击性能的影响。结果表明:同其它几种橡胶常用超弹性模型相比,ArrudaBoyce超弹性模型拟合得到的曲线精度最好。抗冲瓦手性结构的抗冲击性能随着参数μ的增大和λm的减小而降低。

Abstract: According to the hyperelastic theory, the formula of stressstrain was proposed based on ArrudaBoyce strain energy function in condition of one dimensional stress assuming rubber material incompressible. Parameter μ and λm were acquired by using the multilinear regression method with uniaxial compression and tensiling experimental data. Meanwhile, Modelcenter integrated Abaqus was applied to analysis the influence of constitutive model constants on the shock resistance of antishock layer. Results show ArrudaBoyce hyperelastic constitutive model obtained by quasistatic compression and tensiling experiment data was the best wonderful accuracy compare with other common rubber hyperelastic model. The shock resistance proprietary of antishock layer was reduced along with the parameter (increasing and λm reducing.
Key words: ArrudaBoyce strain energy function; viscohyperelastic; rubber; shock resistance;antishock
