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.
