摘要
将模糊集合理论应用于机械零件强度可靠性设计中,分析应力强度干涉模型,讨论机械零件不失效这一模糊随机事件的隶属函数的选取原则与方法,推导模糊可靠度的计算公式,建立了模糊可靠性设计数学模型,并通过实例设计的分析比较,说明模糊可靠性设计的先进性。
Applyinn fuzzy set theory to the reliability of the machine components strength. The stress intensity - interferinn model for analysis, this paper discusses the selectinn principle and method of subordinate functions for the fuzzy random event that machine component ispermanently valid, deduces the calculatinn formula for fuzzy reliability, and to establish the mathematical model of reliability design, and demonstrates with examples the pronress offuzzy reliability design.
