| 摘 要： | 以工程车辆正线动力学性能型式试验数据为研究对象,论述了国内外铁路对车辆横向失稳试验的判定,从车体和构架横向振动加速度、轮轴(轨)横向力及轮轨垂向力3方面对试验过程中车辆横向蛇行失稳时呈现的动力学性能特征进行分析、归纳和总结。结果表明,焊接构架式转向架的工程车辆,采用构架横向加速度10 Hz滤波后,连续峰值5 m/s2来进行横向失稳评判较为合理。

| Abstract: | The dynamics test data of construction vehicle running on the railway line was the research object in this paper.The judgment method and standard of vehicle's lateral hunting instability at home and abroad were discussed in detail.Some dynamic characteristics were analyzed and summarized when the vehicle hunting instability occurred,in terms of lateral vibration acceleration of carbody and frame,lateral force of wheel/axle and wheel/rail,and vertical force of wheel/rail,and so on.Then,as for the constructio... |
