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。
Measuring the geometry of the wheel profile is very important for the safe operation of the train. The laser image method is the current mainstream detection technology for measuring and measuring the geometry of the train wheels. However, the traditional wheel alignment system can not meet the requirements of vehicle layout, mechanical design and camera image quality at high speed , The detection accuracy of laser image method will be affected by the speed of the vehicle. Therefore, the system of traditional wheel alignment measurement system has been improved in terms of system solutions and calibration methods, thus ensuring that when the train passes the high speed, All parameters of the measurement accuracy to meet the requirements.
