    Abstract
  • In order to research the dynamics performance of linear-motor metro vehicle and the suspension characteristics of linear induction motor(LIM), the classical electromagnetic mechanics model and finite element model of LIM, and the multibody dynamics model of the vehicle were established.The longitudinal and lateral end effects and air gap were taken into account in the classical model.Numerical method was adopted to solve the traction force, normal force and pitch moment of LIM.The solution results by the classical model were compared and verified by using finite element method.Simulation result shows that the classical model describes the mechanic properties of LIM and meets the requirement of dynamics simulation for metro vehicle.The dynamic performance of LIM is closely related to the change of air gap and suspension types.Different suspension types have their own advantages and disadvantages.Proper suspension type and air-gap control strategy can increase the stability of metro vehicle, reduce the wheel-rail wear and improve the curving performance of vehicle system.
