摘　　要：为实现智能制造的快速转型,各生产单位纷纷引进数字化生产线。数字化生产线的落成使得数字化设备的在线校准成为保障产品质量的关键环节。以轨道交通轴承数字化测量设备为研究对象,针对使用过程中出现的影响测量结果的重要因素,即传感器漂移、测量环境温度变化和系统重复定位精度,提出基于极限量规的在线校准方法。通过理论分析和试验验证,该方法能有效地补偿各个因素对测量结果的影响,又能对数字测量系统的综合测量能力进行评价,且评价结果满足行业规范要求。To realize intelligent manufacturing,manufacture companies bring in digital manufacturing lines.To make use of the digital manufacturing lines,in-situ calibration and identification of digital system play an essential role.A digital system detecting geometric dimensions of axle bearings are constructed and analyzed.And three factors influencing measuring results are explained,which are changing temperature of measuring environment,zero draft of sensors and repeatability of system.And a time-related and temperature-related in-situ calibration method using limit gauge is introduced to eliminate the influences of factors to measuring results.The proposed method can distinguish the influences of the three factors to measuring results and assess the comprehensive measurement ability of the system,which is verified by experiments.
