摘要

车轮外形几何尺寸的测量对列车的安全运行非常重要。激光图像法是当前主流的检测运行列车车轮外形几何尺寸的检测技术，然而在列车高速通过的情况下，传统的轮对外形尺寸检测系统在系统布局、机械设计和相机成像质量等方面无法满足车速的要求，激光图像法的检测精度会受到车速的影响，因此在系统方案及标定方法等方面对传统的轮对外形尺寸检测系统进行了改进，从而保证了在列车高速通过条件下，系统对车轮各个参数的测量精度达到要求。

Abstract

Measuring wheel profile parameters is very important for the safety of running trains. Inspection of wheel profile parameters with laser light image was the mainstream technology. Under high-speed conditions, however, the tradition dynamic inspection system for wheel profile of railway vehicles couldnot meet the precision demand in several aspects, such as system layout, mechanical design, image quality of camera so on. Several solutions for the dynamic inspection system for wheel profile parameters in calibration algorithm, system design aspects were proposed, which ensured that system precision reached the standard in high speed situations.
