基于故障数据的设备运行可靠性分析与评估
Equipment's operation reliability analysis and assessment based on failure data
摘要
Abstract
The study focused on equipment''s operating reliability analysis and assessment based on equipment''s failure data.The failure data of an automobile manufacturing enterprise''s horizontal machining center were statistically analyzed to form the observed sample data, and the curves of the probability density distribution function and the cumulative distribution function of the equipment''s failure interval are fitted out, so the failure distribution law was deduced that it maybe obey a Weibull distribution.Then through the test of the correlation of the Weibull distribution function, it was confirmed that the fault interval distribution of the equipment obeys the Weibull distribution.Finally, according to the statistical results, the reliability assessment indexes of the equipment were obtained.关键词
