摘　　要：为了研究地铁直线电机车辆的曲线通过性能,建立了直线感应电机的电磁力学模型,在此基础上建立了地铁直线电机车辆机电耦合系统动力学模型,并将其与传统地铁车辆的动车和拖车进行对比研究。仿真结果表明:所建立的直线电机力学模型,可以满足动力学仿真的实时性要求;线路参数和行车速度与车辆曲线通过动力特性密切相关;地铁直线电机车辆和传统车辆相比提高了曲线通过速度,降低了轮缘磨耗,减小了轮轨间作用力,具有良好的曲线通过性能。In order to study the curving performance of linear metro vehicle, an electromagnetic mechanics model of linear induction motor （LIM） is established. On this basis, an electricalmechanical coupled vehicle dynamics model is built, a comparison with the conventional metro motor and trailer car is also conducted. The simulation results show that： the model of LIM can meet the requirements of realtime dynamic simulation; the curve parameters and vehicle speed are closely related to the curving performance; compared with the conventional vehicles, the linear metro could increase curve passing speed, reduce flange wear on wheel, decrease the force between wheel and rail, and thus have better curving performance.
