【摘要】 本文根据新一代产品几何技术规范(简称 GPS)标准体系的要求,建立 GPS 规范的标准链模型,并通过对偶性原理来保证认证操作链和规范操作链的一致,使得方法不确定度简化为零,从而给出了一种 GPS 标准链依从不确定度的计算方法。最后应用此方法对平面度进行了依从不确定度的计算。实验表明,用此方法计算的依从不确定度,可以依据 ISO/TS 14253-1 给出的判定原则定量地进行合格性判定,满足新一代 GPS 标准的要求。更多还原

【Abstract】 To a specific specification for the new generation geometrical product specifications(GPS)system, this paper establishes the model for standard-chain,and keeps the verification standard- chain accordance with the specification standard-chain by duality principle,so that the method uncertainty is ignored.Thus, a calculation method for the GPS standard of complication uncertainty is proposed.And then,this method is employed in the compliance uncertainty calculation of flatness.The finally experimental result indicates that the uncertainty of flatness could be evaluated quantitatively by the decision rules provided by ISO/TS 14253-1,and meets the need of the new generation GPS standard.更多还原
