飞机、汽车等交通工具在操纵性能同高速运行或飞行时的稳定性方面是相互矛盾的,铁道车辆也不例外。所谓操纵性能对转向架来说,就是曲线通过性能,高速运行时的稳定性则是对应于蛇行运动的稳定性。一、转向架的运行稳定性铁道车辆在高速运行时产生称为蛇行运动的自激振动,即使在平整的轨道上,随着速度的增加,车体和转向架也会自然地产生 Vehicles such as airplanes and automobiles are contradictory to maneuverability in terms of stability at high speed or in flight, and rail vehicles are no exception. The so-called maneuverability of the bogie, that is, curve through the performance, high-speed operation of the stability is corresponding to the stability of the serpentine movement. First, the stability of the bogie operation Railway vehicles at high speeds produce a self-excited vibration known as the serpentine movement, even in the flat track, with the speed increases, the body and the bogie will naturally occur
