The invention provides a lift stability control method for a lift wing high-speed train passing through a tunnel, which comprises the following steps: mounting a lift wing on each section of high-speed train, starting to adjust the lift wing attack angle to a second set value when the lift wing attack angle of the train running on an open line is a first set value and the distance between the lift wing and the entrance of the tunnel is a set distance, and after the train drives out of the tunnel, the lift wing attack angle is recovered to the first set value. According to the invention, the train can obtain a better lift-drag ratio when running on the open line, and the friction force between the wheel rails is reduced, so that the abrasion between the wheel rails is effectively reduced, the energy consumption caused by friction loss between the wheel rails is reduced, the service life of railway equipment is further prolonged, and the lift force after the train enters the tunnel is basically the same as that when the train runs on the open line; the lift force of the train running in the open line and the tunnel is accurately, automatically and stably controlled, and the shaking of the train body caused by the fluctuation of the lift force is reduced, so that the service life of the train is prolonged and the comfort of passengers is improved.
本发明提供了一种升力翼高速列车通过隧道的升力稳定性控制方法,在每节高速列车上安装升力翼,当列车在明线运行时的升力翼攻角为第一设定值,当升力翼距离隧道入口为设定距离时,开始将升力翼攻角调整为第二设定值,当列车驶出隧道后,升力翼攻角恢复为第一设定值。本发明能够让列车在明线运行时获得较好的升阻比,降低轮轨之间的摩擦力,从而有效地降低轮轨之间的磨损、降低轮轨之间摩擦损失的能耗,进而提升铁路设备的使用期限,列车进入隧道后升力可与明线时保持基本相同,精确地对列车在明线和隧道内运行时的升力进行自动稳定控制,减少了升力波动带来的车体抖动,从而提高了列车使用期限和乘客舒适性。
