摘要
本文针对圆形截面橡胶悬置胶垫,给出了利用有限元方法和参数识别技术确定压缩刚度经验公式中形状系数的方法与步骤。结合车用发动机悬置,计算得到了橡胶悬置在不同变形量情况下形状系数的经验公式。
Taking a rubber engine mount of rectangular roundness - section as an example, an approach, based on nonlinear finite element method and parameter identification technique, is presented in this paper to calculate the shape factor of the empirical formulae for compressive stiffness of the mount. For a practical rubber engine mount, empirical formulae are established which vary with compression level.
