To verify the battery bracket fatigue life of electric bus , the finite element model of the battery bracket is built, and the equivalent stress distribution of the frame was got. Multi-body dynamics vehicle model was built in ADAMS/Car. The simulation analysis was conducted based on the road spectrum compiled by MATLAB to simulate C level road model. The maximum vertical acceleration of electric car in the road is obtained. The load of the battery bracket is calculated. So as to get the finite element solution. Combined with the random vibration analysis and the results of finite element analysis, the fatigue life of the battery bracket is calculated by combing the material S-N curve. Finally, the battery bracket was evaluated comprehensively according to the strength,stiffness,and cumulative fatigue usage. The results could provide a theoretical basis for future optimization.
