摘　　要：针对动车轮对动态扫描的精度不足与成本过高问题,提出了一种基于激光实时同步扫描动车轮对双侧轮廓,并辅以最小二乘法计算轮对实际圆心的轮廓检测方法。论述了基于zmotion运动控制器的高精度同步扫描控制系统的结构和工作原理。实测表明系统能较高精度地还原动车轮对的实际轮廓并对磨损程度进行评测。Aiming at the problem of low precision and high cost of dynamic scanning of EMU wheelset,a method of contour detection based on laser real-time synchronous scanning of both sides of EMU wheelset was proposed,and the least square method was used to calculate the actual center of the wheelset.The structure and working principle of the high precision synchronous scanning control system based on zmotion controller was discussed.The actual measurement showed that the system could restore the actual profile of the EMU wheel set with high accuracy and evaluate the wear degree.
