| Summary: | 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. |
