摘要/Abstract

摘要： 在分析常见分布适用范围的基础上,对连杆疲劳寿命采用极大似然法拟合分布参数,通过K-S假设检验和相关性分析对参数模型进行优度检验,得出了适于连杆疲劳寿命可靠性分析的通用性分布模型。在该模型的基础上分析了连杆的可靠度、可靠度寿命和平均寿命,得出了该型连杆的B10寿命。建立了连杆疲劳可靠性分析的流程与方法,评估了连杆的可靠度寿命,对连杆的可靠性使用具有重要意义。

关键词: 连杆, 疲劳, 可靠度, 拟合优度, K-S检验, 可靠度寿命

Abstract: Based on the analysis of the common distribution scope,on the basis of the fatigue life of connecting rod using the maximum likelihood method fitting distribution parameters,through the K-S hypothesis test,we test was carried out on the parameter model and correlation analysis,obtained the suitable for reliability analysis of general distribution model of connecting rod fatigue life. In the model,on the basis of analyzing the reliability of connecting rod life expectancy and life expectancy,reliability,it is concluded that the type of B10 life of connecting rod. The establishment of a connecting rod fatigue reliability analysis of the process and method,assessed the reliability of connecting rod life,use of the reliability of the connecting rod is of great significance.

Key words: connecting rod, fatigue, reliability, goodness of fit, K-S inspection, reliability life
