摘　　要：介绍了直线电机地铁车辆的特点,简单分析了直线电机的三向电磁力。考虑到用有限元模拟电磁场得到电磁力在空间上分布的方法的复杂性,结合工程实际需要,基于直线电机推力控制方法,提出一种新的方法,即用直线电机牵引特性曲线模拟直线电机对车辆的作用。最后用SIMPACK仿真牵引工况下直线电机地铁车辆的动力学性能。结果表明用该方法可以简单并且成功地对直线电机地铁车辆的动力学性能进行分析。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.
