So in order to analysis the impact of different alignment on the comfort index, we should establish a dynamic model to make a car-guideway coupling emulation.
因此，为了分析不同线路设计参数对舒适度的影响，应采用车—线耦合动力学模型进行计算仿真。

The non linear moving stability of cars on resilient track is researched with the car track coupling dynamics theory.
运用车辆-轨道耦合动力学理论，研究了车辆在弹性轨道上的非线性运动稳定性问题。
