钢管自动测长的误差分析及解决

Ways of automatic pipe length measurement and its error analysis

分析了钢管自动化车间精整区自动测长设备的两种基本原理:推钢测长和在线测长,并推导了钢管长度的运算公式。根据各种影响因素,以及误差的性质和特点,分别从系统误差、随机误差和临界粗大误差方面,分析了误差的产生来源和误差大小。最后从工程实际应用的角度,提出了解决或缩小各种误差的方法。

Two ways of steal pipe automatic length measurement were presented, and the influencing factors was analyzed. According to the influencing factors, the source of errors in three different type was analyzed, and the size of different error was calculated. At last, some useful methods to deal with the errors were presented.
