环形橡胶径向刚度特性仿真分析

Radial Stiffness Characteristics Simulation Analysis of Annular Rubber

利用ANSYS软件建立了环形橡胶的有限元参数化模型,将对模型仿真所得结果与已有数据进行对比,验证了仿真模型的正确性,实现了环形橡胶径向刚度的快速计算.在此基础上,分析了内外圆柱面半径与轴向长度对环形橡胶简化径向刚度值的影响,研究了环形橡胶的径向刚度特性,确立了在环形橡胶实际设计中需要考虑的要点,为环形橡胶的设计提供了依据.

The finite element model of annular rubber based on ANSYS is built up. And the cantrast between the experimental data which are available is made and the analysis results of the finite element model verifies the validity of the model. The fast calculation of the rubber bush radial stiffness is achieved. Based on this model, the radial stiffness characteristics of rubber bush are studied by analyzing the influence of inner and outer radii and axial length on the non-dimensional values of radial stiffness. And several conclusions are drawn, which provide guidance for the design of the cylindrical rubber bush.
