摘　　要：在高速铁路试验线路,实测典型高速动车组及受电弓在不同运行速度和曲线半径下受电弓动态抬升量和横向摆动量。通过实测数据分析得出:受电弓动态抬升量和横向摆动量随着速度增加而增加;动车组达到线路设计速度后,随着曲线半径增加,横向摆动量变大,曲线半径越大受电弓向外轨方向摆动趋势越加明显;最大动态抬升量更容易出现在直线区段,最大横向摆动量更容易出现在曲线区段,且最大抬升量和最大摆动量与速度有明显关系。通过分析实测数据及测量未考虑的偏差,高速铁路受电弓动态包络线标准限值能够满足安全性要求。On the high-speed railway test line,the dynamic lifting and lateral swing of typical high-speed EMU pantograph was measured at different operating speeds and curve radii.Through the analysis of measured data,it can be concluded that the dynamic lifting and lateral swinging of the pantograph increase with the increase of speed;After the high-speed train reaches the designed speed of the line,as the curve radius increases,the lateral swing increases,and the larger the curve radius,the more obvious the trend of the pantograph swinging towards the outer rail direction;The maximum dynamic lift is more likely to occur in the straight section,and the maximum lateral swing is more likely to occur in the curve section,and there is a clear relationship between the maximum lift,maximum swing and speed.By analyzing the measured data the unconsidered deviations,the standard limit values for the pantograph kinematic envelope of high-speed railway can fulfill its safety requirements.
