摘要:

针对电连接器接触对数量较小的情况下,其接触寿命不适宜用Weibull分布描述的问题,研究了串联结构产品可靠性建模及统计分析方法,建立了任意接触对数量下电连接器接触寿命分布的可靠性模型,研究了基于区间数据的模型参数点估计和Bootstrap区间估计方法。试验研究结果表明:对于串联结构产品,采用串联结构的真实分布比近似地采用威布尔分布的拟合优度高,可更加客观地评价产品的可靠性水平。

Abstract:

Due to  the small number of electrical connector, the contact reliability  life  could  not be described by the Weibull distribution model.This paper studied a new reliability modeling and statistical method, as well as the model parameter point estimation and Bootstrap interval estimation method for the reliability life analysis of any given  numbers  of  electrical connector.The results were verified by the experiments and show that  the real distribution may evaluate more accurately than Weibull distribution approximation model for the series structural products.

Key words: electrical connector, series system, reliability modeling, statistical analysis
