摘　　要：以同一角速度和方向转动主动轴和从动轴时,激光束在接收器光敏面上的轨迹就会形成封闭的曲线.该曲线任一点的坐标由两轴的相对位置决定,从这一观点出发建立了激光对中的数学模型.采用单光束、一个探测器的激光对中测量仪的数据采集系统和数据处理模型,根据输入计算机的安装参数,经过较为复杂的计算与修正可求得两轴间状态参数,通过计算机可计算出被调整机器的四个机脚在水平面内与垂直面内移动的修正量,移动机器使轴对中.The laser beam＇ s track which is on photosensitive surface of the receiver will be closed curve, when the drive shaft and the driven shaft rotate with the same angular velocity and rotation direction. The coordinate of arbitrary point which is on the curve is decided by the relative position of the two shafts. Basing on the viewpoint, sets up the mathematic model of laser alignment. Using the data acquisition system and the data processing model of laser alignment meter with single laser beam and a detector , basing on the installation parameter of the computer, can gain the state parameter between the two shafts by more complicated calculation and correction. The correcting data of the four under chassis of the adjusted apparatus moving on the level and the vertical plane can be calculated using the computer. This will instruct us to move the apparatus to align the shafts.
