Abstract Dynamic coupling between movement pairs with clearance in steering mechanism of the vehicle can make great influence on its dynamic response. Based on analytical mechanics, a 6-DOF dynamic model of vehicle shimmy system with consideration of dynamic coupling between two movement pairs with clearance is established. Numerical analysis is carried out to evaluate the dynamic response of vehicle shimmy system. Some phenomenon such as Naimark-Sacker bifurcation and chaos for the system are discussed, and the dynamic mechanism for vehicle shimmy is investigated in view of energy transfer. The conclusions can provide theoretical basis for attenuation of vehicle shimmy.
