摘要
根据以往研究成果,从不同本构模型的应用优缺点考虑使用Mooney-Rivlin二参数本构模型建立橡胶材料有限元模型,并通过实验验证了模型的正确性。通过动静刚度对比计算,验证了静态刚度计算方法在性能分析中的可行性。建立了不同结构参数的隔振圈有限元模型。然后,在ANSYS软件中对隔振圈各个方向的刚度值进行了仿真计算。计算结果表明:不同结构参数对各方向刚度的影响规律各不相同,而且径向刚度和轴向刚度之间存在刚度变化耦合的现象。最后,根据分析结果提出了调整隔振圈刚度的方法,该方法对提高隔振圈减振效果以及隔振圈的推广具有一定的参考价值。
Based on the past studies, a rubber FE model is established by using the two-parameter Mooney-Rivlin constitutive model in view of the features of different constitutive models. The model is proved to be correct through experiment or tests. The static-dynamic stiffness contrast verifies the feasibility of the static stiffness calculating method in performance analysis. Then, different structure parameter models are constructed to calculate different direction stiffness of isolator ring in ANSYS software. The calculated results show that the impact of every structure parameter on different direc- tion stiffness is not the same and that these is a coupling phenomenon of stiffness change between axis stiffness and radius stiffness. Finally, a method of adjusting the isolator ring stiffness is proposed. The method is of certain reference value to improving the effect of the isolator ring and promoting its application.
