For the mobile case, a dynamic model of the vehicle motion, which takes account of the relationship between the rigid body motion of vehicle and the steering and drive rates of wheels, is adopted.
The simulation results also show that the running stability of the vehicle system under the resilient track conditions is better than that under the rigid track conditions.
仿真结果还表明，车辆系统在弹性轨道条件下的运行平稳性优于刚性轨道条件下的运行平稳性。
