摘　　要：本研究根据WH150橡胶隔振器的动静态实测数据,通过Abaqus与Isight联合仿真,反演弹性材料的超弹本构参数和黏弹本构参数。输入反演的橡胶本构参数,建立橡胶隔振器的预测模型,该模型推导出的三向静刚度、动刚度和动态传递率误差均小于10%。将预测模型应用于隔振器实际使用工况的计算中,可快速评估橡胶隔振器的实际共振频率和疲劳寿命。Based on the measured dynamic and static data of WH150 rubber isolators,the hyperelastic and viscoelastic constitutive parameters of the elastic material are inversed through the joint simulation of Abaqus and Isight.With the rubber constitutive parameters as input,a prediction model of the rubber isolators is established.The errors of the three-way static stiffness,dynamic stiffness and dynamic transmissibility derived from this model are all less than 10%.By applying the prediction model into the actual working condition of the rubber isolator,the actual resonance frequency and fatigue life of the rubber isolator can be quickly evaluated.
