介绍了一种气电测量应用于曲轴综合测量的方法,简述了检测原理和系统结构,给出了测量程序流程图。通过测试和生产现场使用表明,所测47个参数均满足测量要求,其准确度误差最大为2μm,扩展标准不确定度为1.48μm。
A method of measuring gas and electricity used in integrated crankshaft measurement is introduced. The principle of detection and system structure are briefly introduced. The flow chart of measurement procedure is given. Through testing and production field use shows that the measured 47 parameters meet the measurement requirements, the accuracy of the maximum error of 2μm, extended standard uncertainty of 1.48μm.
