摆式客车曲线通过动力学研究

study on curving behavior for tilting passenger car

采用摆式客车 ,可使列车以较高的速度通过曲线且不降低旅客的乘坐舒适度 ,这是既有线路提速、增加铁路客运能力、提高铁路与其它交通工具竞争能力的一种有效方法。摆式客车曲线通过速度的增加必然引起车辆过曲线时的轮轨横向力、整车磨耗功指数的增大 ,径向转向架是解决这一问题的有效途径。本文建立了装有自导向转向架的摆式客车系统的动力学计算模型 。

By using tilting carbodies, the train can negotiate at a higher speed without reducing the passenger's ride quality. This is a good method, which allows a significant increase in speed at existing track, improves the railway transport capability, and enhances railway's competition with other transportation. With the increase of curve negotiation speed, the wheel/rail lateral force and wheel/rail wear index will increase. Radial bogie is an effective way to solve the problem. In this paper, the dynamical model for the tilting carbody with self steering bogie is established, and the curving performance of the car is investigated.
