Test Design and Study of Center Pin Plate Type Traction Device

The mechanical performance test of the traction device is an important means to improve the dynamic performance of the vehicle bogie. The structure and principle of a center pin plate type traction device are introduced. A new system loading test plan is designed. The longitudinal, vertical, lateral stiffness and fatigue performance of the traction device are studied, and the traditional traction rubber pile pair is applied. The test is compared and analyzed. The test results show that the test design is consistent with the actual working conditions. The system test can more accurately reflect the mechanical properties of the traction device, and the performance meets the requirements. At the same time, the stiffness of the traction device is less than the stiffness of the traction rubber pile. The experimental research results play a guiding role in the development and testing of traction device products.
