Abstract The excellent performance of super capacitor makes it more and more important to load in rail transit vehicles. In order to adapt to the compact and high lightweight requirements of super ca-pacitor energy storage cabinet, the strength simulation and fatigue life prediction of the cabinet structure become more and more complex and significant. For a train energy storage cabinet, ac-cording to the Standard IEC 61373-2010, the finite element analysis software is used to simulate the stress in the process of impact test by mode superposition method. The response under ran-dom vibration environment is calculated, and the maximum Von Mises stress of 1σ, 2σ, 3σ is ob-tained. Based on the S /N curve of the material, the fatigue life of the structure under the given random vibration environment is estimated based on the Gauss distribution and linear fatigue cumulative damage theory proposed by Miner. The results verify the feasibility of the simulation method and provide the basis for the safety and reliability design of products. Keywords
