本文根据保角变换原理,将固筒状橡胶轴承变换成长方体橡胶元件。求出了使橡胶内表面沿载荷作用方向产生单位位移所需加的径向集中力的大小,此力值就是橡胶轴承的径向刚度。考虑了橡胶材料的不可压缩性质。通过例子说明了本方法的精确性。给出了公式推导中的假设和公式适用的条件,并对一些问题进行了讨论。 According to the principle of conformal transformation, this paper transforms the solid cylindrical rubber bearing into a cuboid rubber element. The magnitude of the radial concentrated force required to displace the inner surface of the rubber along the direction of the load is calculated as the radial stiffness of the rubber bearing. Considered the incompressible nature of rubber materials. The accuracy of this method is illustrated by examples. The assumptions and formulas for formulating formulas are given, and some problems are discussed.
