| Summary: | Starting from the failure of imported rubber elastic components used in a linear motor bogie, the domestic development of the rubber elastic components was carried out. The advantages and disadvantages of different structures of the primary rubber traction joints were studied and discussed. The fatigue characteristics of natural rubber and chloroprene rubber at 70 ℃ high temperature were analyzed and compared. The stress and strain of rubber under working load were simulated and calculated by finite element analysis software. A traction joint with close structure was presented. Compared with the laminated structure, the rubber strain of the structure was reduced by more than 15% by finite element analysis. At the same time, the fatigue tests of two structures at room temperature and high temperature were carried out. The results showed that the fatigue performance of the optimized products has been improved by more than three times. |
