In the traditional vehicle system dynamic analysis, the influence of harmonic torque of traction motor is rarely considered.In fact, the harmonic torque can cause the motor rotating speed’s oscillation, and then generate dynamic action forces exerted on the vehicle system.In order to calculate harmonic torque of a traction motor and its effects on dynamic performance of high-speed trains, according to traction motor’s parameters of a certain type high-speed train in China, the first four order components of its harmonic torque were calculated and added to the vehicle system dynamic model.After calculation, it was found that the harmonic torque has a larger influence on the comfort, wear and dissipation work indexes of a vehicle system; it has little effect on the system’s critical velocity, transverse and vertical ride indexes, derailment coefficient and maximum axle lateral force; it also causes longitudinal acceleration root mean square values of gear box and traction motor to increase, the harmonic torque’s effect on them increases with increase in the traction motor’s rotating speed.
