地面测试轮轨冲角的研究

The Research of Mesuring the Attack Angle on the Ground

本文从考虑轮轴与曲线半径方向之间的夹角和轮轨冲角相等这一原理出发，详细叙述了用激光、计算机技术测量冲角的方法，并从理论上对测试信号的处理、测试误差的分析进行了讨论，最后得到了实际测量结果。

Considering the equlity equality between the attack angle and the anglebetween the wheel set axleand the direction of the curve radius,this paper details the method of using the laser and computer technigue to measure the attack angle between the wheel and the rail,and deseribes how to deal with the measure signal and analyze the measure error. Finally,it deseribes the actual attack angle measure value.
