摘　　要：针对橡胶超弹性导致恒切深砂带的磨削材料去除深度与理论材料去除深度产生误差的问题,基于连续介质力学理论模型的本构方程对橡胶超弹性特性下的应力-应变关系进行分析,对比确定了适用于钢轨打磨作业的Mooney-Rivlin理论模型,揭示了橡胶超弹性和线弹性的关系和差异,利用仿真验证了上述理论模型的正确性。In view of the error between the grinding material removal depth and the theoretical material removal depth of the constant cutting depth abrasive belt caused by the rubber hyperelasticity,this thesis analyzes the stress-strain relationship of rubber based on the theoretical model of continuum mechanics.The Mooney-Rivlin theoretical model suitable for rail grinding is determined by comparison.The relationship and differences between rubber superelasticity and linear elasticity are revealed,and the above theoretical model is verified using simulations.
