摘要

针对当前涡轮导向器喉道面积三坐标测量不确定度评估研究的不足，通过分析测量过程和测量原理，给出了一种涡轮导向器喉道面积三坐标测量不确定度评估模型。最后结合测量实例对单喉道面积测量不确定度及全环面积测量不确定度进行了评估。评估结果表明，所选用的三坐标测量方法可以满足涡轮导向器喉道面积的设计要求。

Abstract

For the shortage of the current study on measurement uncertainty evaluation of turbine nozzle throat area measured by coordinate measurement machine (CMM)

a measurement uncertainty evaluation model of turbine nozzle throat area measured by CMM was proposed by analyzing measurement procedure and principle. Finally

measurement uncertainties of single throat area and area of all throat in circle were evaluated according to a measurement case. The evaluation result shows the CMM method could meet the design requirement of turbine nozzle throat area.
