闸门开度示值误差测量结果的不确定度评定

Evaluation of Uncertainty about Error of Gate Opening Measure Results Indication of Gate Opening Gauge

介绍了闸门开度计闸门开度示值误差测量结果的不确定度评定方法。按照测量不确定度的传播规律建立数学模型,通过对各分量标准不确定度分析计算,实现对不确定分量的汇总,求出合成不确定度和扩展不确定度。结果表明,闸门开度示值为1.0m时,扩展不确定度为4.02m。

The article introduces a way of evaluating uncertainty about error of Gate Opening measure results indication of Gate Opening Gauge.Based on uncertainty regulations,a mathematical model is built.From annlysis and calculation of each standard uncertainty,the collection of uncertainty components is realized.And finally,combined standard uncertainty and expanded uncertainty are obtained.The results indicate that U is 4.02 mm,as gate opening gauge is 1.0 m.
