description The invention discloses a vibration reduction design method for a hub motor driven vehicle. According to the technical scheme, the method comprises the steps of building physical and mathematic models of vibration of the vehicle according to the existing hub motor driven vehicle; building road surface and hub motor electromagnetic force models; through simulative analysis, performing calculation to obtain vibration energy and contribution rate of each key point under road surface and motor excitation; according to an analysis result, proposing a feasible improvement scheme, and through comparative analysis, determining an optimal scheme; obtaining sensitive parameters of vibration energy transmission of the optimal scheme; by taking minimum vibration energy transmitted to a vehicle body as an optimization goal, performing optimization design on the sensitive parameters by adopting a proper optimization algorithm; and through comparative analysis before and after optimization, verifying an optimization result,
