    Abstract:

    Vibration differential equation of a novel wheel drive system with a swing motor as dynamic damper was deduced, its three degree of freedom (DOF) vibration model was established both in MATLAB and ADAMS software, then body acceleration and wheel dynamic load power spectrum density (PSD) were simulated and analyzed, and accuracies of theoretical equation and simulation model were verified. Then its effect on improving vehicle comfort and wheel ground adhesion were compared with normal In wheel drive system (IWD) based on body acceleration and wheel dynamic load power spectrum density. The results show body acceleration and wheel dynamic load power spectrum density of this novel wheel drive system are lower, and vehicle ride comfort and ground wheel adhesion are improved apparently.
