The invention discloses an aerodynamic lift collaborative train lift wing system based on high-speed rail clearance constraint. The aerodynamic lift collaborative train lift wing system comprises a lift wing system body. The lift wing system is mounted at the top of the train and limited below the contact network; each compartment of the train is provided with the same lift wing system. And the heights of a plurality of horizontal lifting wings in the lifting wing system are equidifferently increased from the front end of the carriage to the rear end of the carriage. Through the synergistic effect of the lift wings installed on the upper portions of the train carriages, upward lift perpendicular to the ground is generated, so that the pressure between high-speed train hubs and rails is greatly reduced, the carrying capacity of a high-speed train is improved, and the loss of the train hubs and the running cycle cost of the train are reduced. By adopting a gradually rising layout mode, the aerodynamic interference among a plurality of lift wings is effectively reduced, so that the aerodynamic performance of the lift wing system is ensured, the lift wings are ensured to generate enough lift force, and the pressure of a train on a rail is greatly reduced.
本发明公开一种基于高铁限界约束的气动升力协同列车升力翼系统,包括升力翼系统;升力翼系统安装于列车顶部且限定于接触网下方;列车每一车厢上均安装有相同的升力翼系统;升力翼系统内若干水平升力翼高度由车厢前端向车厢后端等差上升。本发明通过安装在列车车厢上部的升力翼协同作用,产生垂直地面向上的升力,从而大大减少了高铁轮毂与轨道间的压力,增大了高速列车的运载能力,降低了列车轮毂损耗及列车运行周期成本。采用逐渐升高的布局方式,有效的减少了多片升力翼之间的气动干扰,从而保证升力翼系统的气动性能,保证了升力翼产生足够的升力,极大程度减少了列车对铁轨的压力。
