【摘要】 为解决零部件内腔气密性检测设备个性化设计周期长、设计质量不稳定、生产成本高等问题,分析了气密性检测原理及检测设备设计过程,阐述了基于被测件分类基的可适应设计方法。提出一种携因素聚类方法,该方法采用层次分析法确定影响因素权向量,通过设定被测件关于各影响因素的吻合度,得出了被测件对相似度的加权计算方法,给出了聚类准则。阐述了循序聚类的分类基规划过程,并研究了该方法的软件实现。实例表明,该方法可有效规划被测件分类基,为可适应基型设计提供支撑。更多还原

【Abstract】 To solve the problem of long period,high production cost and unstable quality in gas tightness detecting equipments,the design processes of detecting principle and detecting equipment were analyzed,and the adaptable design method based on classified base was described.A factor-considered cluster method which could determine the weight vector of factors by Analytic Hierarchy Process(AHP)was put forward.Through setting the consistency degree of tested parts on each factor,the weighted algorithm for similarity was obtained,and the cluster norm was given.The process of iterative cluster algorithm was explained,and the software based on the method was developed.Cases showed that the proposed method was effective in planning the classified base,which could be used to support the adaptable product case design.更多还原
