中文摘要：

基于铁道车辆-轨道耦合动力学理论,建立考虑轮轨力、直线电动机感应线圈和感应板之间电磁力两种耦合关系的地铁车辆-板式轨道耦合系统动力学模型。模型包括车辆子系统、板式轨道子系统和直线电动机子系统三个部分。运用该动力学模型,研究曲线参数对车辆曲线通过性能的影响。分析结果表明：曲线半径、外轨超高和行车速度共同影响车辆曲线通过性能,车辆曲线通过为平衡状态时,整体曲线通过性能达到最佳;基于安全性的角度,应尽量避免车辆曲线通过处于欠超高状态;轨距加宽处于合理的范围可以提高车辆的曲线通过性能。

英文摘要：

The linear motor metro vehicle-slab track coupling dynamic model is established based on vehicle-track coupling dynamic theory, in which two kinds of coupling relationships with wheel-rail forces and electromagnetic forces between induction coil and plate of linear motor are considered. The model includes the vehicle subsystem, the slab track subsystem and the linear induction motor subsystem. The effect of curved track parameters on the curving performance of the vehicle is studied by using this model. The results show that curving performance of the vehicle is affected jointly by the curve radius, the curved track super-elevation and the curving speed. The overall curving performance of the vehicle reaches the best when the vehicle is under an equilibrium state. From the safety point of view it should be avoided that vehicle is in a track cant deficiency state. And a reasonable gauge widening can improve the curving performance of vehicle.
