轮对安装偏角对高速铁道车辆动力学性能的影响
Influences of Wheelset Defection Angle on Dynamic Performance of High- speed Railway Vehicle
摘要
Abstract
In order to investigate the influences of wheelset defection angle on dynamic performance of high-speed train,this paper analyzed the stress distribution of wheelset with defection angle and the effects of motion tracing as it progresses in theory at first. A dynamic model was built up by SIMPACK based on high-speed rail-way vehicle in our country. It analyzed the influences of wheelset defection angle on dynamic performance in straight track and curve passing separately. And it draws a conclusion that the 1st and 2nd wheelset will deviate from the rail central line in reversed deflection with the defection angle of 1st wheelset,reducing the operation safety. The ride stability has less been affected by small wheelset defection angle,but largely impacted on stabil-ity when the angle is greater than 1mrad;Defection angle will cause certain negative effects on curve passing, and the effects increase with the angle. So the defection angle should be minimized for high-speed train as far as possible to control it within 1mrad.关键词
