直升机动部件结构系统的疲劳寿命可靠度分配方法

An assigned mcthod for the fatigue-life reliability of structural system of helicopter dynamic components

本文引入一种称之为模糊重要度分配的直升机动部件结构系统的可靠度分配方法。这种方法利用模糊数学原理来处理各因素对可靠度分配的综合作用。解决了直升机动部件因可靠性统计数据的缺乏而难于有效地进行可靠度分配的困难,给出了一个适用于直升机动部件结构系统疲劳寿命可靠度分配的工程方法。

This paper presents an assigned mathod for the fatigue-life reliability of structural System of helicopter dynamic compoments called fuzzy impor- tance assignment.This method can Solve the diffi- culty of effectively assigned reliability of helicopter dynamic components due to the lack of reliability Statistical data.This paper gives an engineering method of the fatigue-life reliabily assignment of structural System of helicopter dynamic components.
