The features of the metro vehicle with linear motor were introduced. Electromagnetic forces in three directions were simply analyzed. Considering the complexity of the method to obtain the electromagnetic force on the space distribution by simulating electromagnetic field with FEM, combined requirements of engineering practice, a new method was introduced based on the DTC control system which simulated the effect on the vehicle by using the measured traction performance curves of LIM. The dynamic performance of the metro vehicle with linear motor in traction condition were simulated in SIMPACK. The result showed that the new method could be simply and successfully applied to analyze dynamic performance of metro vehicle with linear motor.
