Weibull分布在机电产品或系统失效分析中的应用

THE APPLICATION of WEIBULL DISTRIBUTION in FAILURE ANALYSIS for MECHANICAL and ELECTRICAL PRODUCTS or SYSTEMS

本文扼要介绍Weibull分布的特点以及在某些机电产品或系统失效分析中的应用。主要通过对机电产品失效寿命数据的分析,找出其失效寿命分布规律,并检验其适用性,从而可定量地分析计算与产品质量密切相关的可靠性指标。文中通过五个实例来说明方法的应用。整个计算过程采用计算机进行,便于在工程上的应用。

This paper briefly describes the features of the Weibull distribution and its application in the failure life amalysis of some mechano-electronic products and systems. The failure life distribu- tion regularity , the suitbility of which has been proved, found by analiging the data of the failure life of the mechano-electronic products, can be used in the quantitative analysis and the calculation of the reliability greatly concened with the quality of the products. The method is illustrated by five ex- amples in. this paper. In order to use in the engineering conveniently, the date are treated by the mi- crocomputer.
