模糊数学在机械零件设计中的应用研究

A Study on Utilization of Fuzzy Function in Designing a Part

传统可靠性设计理论认为处于工作过程中的机械零件 ,要么是安全的 ,要么是失效的。针对这个问题 ,首先从零件失效实质的角度 ,指出了它的不足 ;然后在此基础上 ,运用模糊数学的知识 ,提出了模糊可靠性设计的概念 ,并推出与其相应的数学表达式。

According to the traditional probability theory, a part in the course of working may be either in safe or in invalidation. To counter the above problem ,the paper first points out its shortcomings from the angle how a part is invalidated,then makes use of the knowledge of Fuzzy maths to put forward the notion called Fuzzy probability design and give the related formula.At last it also gives an example how to design a part by the above method.
