摘要

随着材料科学技术的进步，橡胶配方中的各种材料、工艺和胶粘剂得到了长足发展，金属橡胶粘结强度甚至可以超过橡胶本体强度，这导致机车橡胶堆可尝试采用新型的橡胶自由外型面。以一个典型的机车二系橡胶堆刚度设计为案例，提出了一种利用有限元分析方法进行垂向刚度设计的新方法。在材料参数、结构型式和接口尺寸不变的条件下，仅通过橡胶自由外型面的“外凸”型设计，就显著调整了橡胶堆的垂向刚度性能，初步探讨了这种橡胶堆刚度性能设计的新方法和新思路。

Abstract

With the development of material science technology, the various materials, process methods and adhesives of rubber formula have been developed as well. The bond strength between rubber and metal can even exceed the tensile strength of the rubber itself, which results in the rubber free profile of convex shape could be adopted in the design of locomotive bearer spring. Taking the design of classic bearer springs as an example, a new design approach of the vertical stiffness with the FEA method was proposed. The new method and the new idea of the approach proposed based on the research was discussed that the vertical stiffness of bearer spring can be changed significantly when the rubber free profile was designed to be convex shape under the condition of unchanged material parameters, structure type and interface size.
