基于威布尔分析的汽车单一零件失效模式预测方法

A Predict Method of Single Part Fail Mode on Automobile Based on Weibull Distribution Analysis

主要介绍了一种以威布尔保质分析来对汽车单一零部件失效模式进行预测的方法,通过在样本既定的失效模式下,应用威布尔分布对失效数据进行分析,从该失效模式的样本数据中估计出产品或者零部件的重要寿命特征,应用该重要寿命特征参数,进而预测在既定的保有量状况下,未来一段时间或者某一时刻产品或零件的失效率。

In this paper, a predict method was introduced for single part fail mode on automobile which was based on weibull distribution warranty analysis, for a certain fail mode, weibull distribute was used to analyze the samples of fail data, the important life data parameters of this pat or product was gotten, which has the same fail mode. And then these parameters were used to predict the failure rate of this part or product for the whole sample space in or at some time under the same condition.
