The invention provides a method for improving running speed by realizing a semi-suspension flight state of a high-speed railway motor train unit, a wing group is added on a train body of the high-speed motor train unit to provide lifting force required by suspension of the train body, and a bogie of the existing high-speed motor train unit is improved to adapt to the semi-suspension flight state of the train body. By means of the method, after an existing high-speed motor train unit train is improved with low cost, low energy consumption and low technical difficulty, the train body is suspended on the train rail, wheel rail acting force caused by axle load is eliminated, the problems that the existing high-speed motor train unit train needs large driving power, large wheel rail acting force and the like are solved, and meanwhile contact vibration and snaking vibration are reduced. The driving mode of the train is changed to adapt to the semi-suspension flight running state of the train, the running speed of the high-speed motor train unit train can be increased, and ultra-high-speed safe running of the train is achieved.

    本发明提供一种高速铁路动车组实现半悬浮飞行状态来提高运行速度方法,是在高速动车组列车车体上增加翼组以提供列车车体悬浮所需升力,改进现有高速动车组列车的转向架以适应列车车体半悬浮飞行状态。本发明的方法能实现现有的高速动车组列车经低成本低能耗低技术难度改进后,车体悬浮于车轨上,消除因轴重引起的轮轨作用力,解决现有高速动车组列车所需驱动功率大、轮轨作用力大等问题,同时减轻接触震动和蛇行震动。本发明改变列车的驱动方式,适应列车的半悬浮飞行运行状态,有利于提高高速动车组列车的运行速度,实现列车的超高速安全运行。
