摘　　要：我国航天制造业的进一步发展对航天产品制造质量一致性提出了更高的要求。以某航天用贮箱为研究对象提出了一种制造质量一致性评价方法。根据贮箱产品的设计要求和结构特点建立了产品几何精度控制指标体系。针对贮箱产品单件制造的实际情况,综合Bootstrap估计和极差估计的特点,提出了一种综合估计方法,建立了贮箱产品单一几何精度的评价指标。基于所建立的产品几何精度控制指标体系,将体系中各评价指标的估计值求和,作为贮箱产品制造质量一致性评价指数。最后通过评价实例表明了该方法的实用性。With the rapid development of aerospace industry, there is a need to study the consistency of the aerospace products. A consistency evaluation method was proposed for the aerospace tank＇s production. A quality evaluation system was constructed based on the technical requirements and structural features of the aerospace tank. A comprehensive estimation method, based on the range estimation method and Bootstrap estimation method, was presented to evaluate the single quality index of the tank. A comprehensive evaluation index, CII （Continuous Improvement Index）,was proposed to evaluate the consistency of aerospace tanks based on the single tank＇s quality data. An evaluation case shows the effectiveness of the proposed method.
