摘要

摘要: 测量不确定度是产品几何量技术规范(GPS)不确定度的重要组成部分,位于规范限附近存在一个不确定区,位于不确定区的测量结果会出现一定概率的误判现象。在测量不确定度基础上,提出了将ISO/TS 14253-1制定的按规范检验合格与不合格的判定规则应用于自动检测分选技术中。与传统的极限判定原则相比,本文给位于不确定区的测量结果提供了一个合理有效的判定原则,误判现象得到明显改善。本文以自主研制的活塞环自动分选仪作为实验平台,分别按照极限判定原则与按规范检验合格与不合格的判定规则对活塞环闭口间隙进行自动检测分选。结果表明:将测量不确定度应用于自动检测分选技术中,可以明显改善由于存在测量不确定度所引起的对测量结果误判的现象。

Abstract: Measurement uncertainty is one of the most import parts of Geometrical Product Specifications (GPS)uncertainty, it will generate a region of uncertainty and affect the judgment of qualified and unqualified products.This paper proposes new rules to judge the products on the basis of measurement uncertainty. It is based on ISO/TS14253-1. Against the traditional rules, which has considered pure data can be produced in inspection systems, thispaper applies measurement uncertainty in automatic inspections. This paper takes the machine developed by thelaboratory as the experiment platform, inspects the end gap of piston ring based on the traditional rules and the newrules respectively. According to the experimental results, automatic inspections based on measurement uncertaintycan effectively reduce the misjudgments.
