Structural Improvement of the Braking System of Electric Locomotive Based on FEM Analysis
In practice, the large lever, connecting bolt, small lever pin, small lever and front support pin of the brake system of an electric locomotive often broken or fractured. According to the dynamic and static analysis, the maximum stress values of above-mentioned structures were close or exceeded their yield stress. It was consistent with the actual. Based on the result of finite element analysis, combined with the need of manufacturing process, the structure of those components was improved. Simulation and experiment results have indicated that the improved braking system has enough strength and stiffness.
