Abstract: A multi-in-one electric drive system is innovatively designed, which consists of nine parts: motor, reducer, motor controller, DC/DC converter, vehicle charger, high voltage distribution box, vehicle controller, compressor and water pump. The CAE simulation analysis of the electric drive system was carried out, and the key components that did not meet the requirements were improved. The simulation results of the improved system show that the static analysis results, sweep frequency vibration analysis results, random vibration analysis results, impact resistance analysis results, fatigue analysis results and maximum fatigue damage value of the system meet the requirements. The study provides theoretical reference for high performance integration, cost reduction and high efficiency of the electric drive system.
