ABSTRACT–In this paper, the spatial arrangement of a wheel drive system with a swing motor as dynamic was evaluated through the specific system design; by deriving its kinetic equations and establishment three degrees of freedom vibration in MATLAB software, the operating conditions of swing motor was analyzed. Under the New European Driving Cycle (NEDC) condition, the time domain response was acquired through Simulink system. Then with the target of the body acceleration, wheel dynamic load and vibration condition of motor, dynamic vibration absorber’s stiffness and damping were optimized. Then its effect on improving vehicle comfort and wheel ground adhesion were compared with in-wheel motor system based on body acceleration and wheel dynamic load. The results show that the distributed drive system with a swing motor as dynamic is feasible, and vehicle ride comfort and ground adhesion are improved effectively.
