高度卡尺示值误差校准的一种新方法

A New Method for Calibration of Height Caliper Deviation

本文介绍了高度卡尺示值误差校准的新方法—直接测量法。针对JJG31-2011《高度卡尺检定规程》规定的检定方法标准量块法在实际应用中存在的不足,独创性地提出了直接测量法,并依据JJF1059.1-2012《测量不确定度评定与表示》,对标准量块法和直接测量法分别进行了测量不确定度分析,得出直接测量法更为简单、准确。

This paper introduces a new way to calibrate the indication error of the height calipers-direct measurement method.Aiming at the deficiency on the practical application of the standard gauge block method,which is specified by the JJG 31 - 2011"Verification regulation of height caliper".This paper presents an ingenious method of direct measurement,and according to the JJF 1059.1 - 2012" Evaluation and expression of uncertainty in measurement",the uncertainty analysis of the standard gauge block method and direct measurement method is carried out.The result shows that the direct measurement method is simpler and more accurate.
