| 摘 要： | 为保证车辆与钢轨具有较理想的轮轨接触关系钢轨需定期打磨，打磨量是一个重要指标。为获取打磨量，需在打磨前后各测量一次钢轨，这两次测量中仪器定位位置可能不同，从而计算出的打磨量会有较大误差。针对这种误差提出一种仪器定位误差矫正方法，并将该法编程嵌入到轮轨测量分析软件中，经仿真测试及实测仪器验证，该法能高精度地矫正误差。

| Abstract: | The rail needs to be modified regularly for the purpose of keeping good wheel-rail contact relationship, and the rail wear amount is an important index obtained before and after modifying the rail, which may be influ-enced by different positioning of the measuring instrument with some deviation. A method is presented in this pa-per to correct the positioning deviation. The verification tests show that this proposed method is feasible in high-precision positioning deviation correction of rail wear measurement. |
