摘　　要：研发了一种激光同轴度测量系统。建立了一套数学模型，分析了3种不对中情况下的轴-轴同轴度测量方法，推导了测量方程，实现了只需在小角度范围内旋转即可得出轴-轴同轴度的平偏量和角偏量。并提出了孔-孔同轴度的测量方法，实现了用一套设备可以同时测量轴-轴、孔-孔同轴度。A kind of laser coaxiality measurement system is designed. Three disalignments are analysed and the measurement equation is obtained by establishing a set of mathematical models. The axis-to-axis coaxiality deviation is obtained by rotating transmission shaft in a little angle range. The measurement of hole-to-hole coaxiality is also introduced. The measurement of axis-to-axis and hole-to-hole coaxiality can be obtained simultaneously by one set of equipment.
