摘要：
介绍了国际上五种简化疲劳极限应力(σm-σa)图,分析了Good man图、简化疲劳极限折线图、Soderberg直线图、Биргер抛物线图和Gerber抛物线图应用特点。针对Gerber抛物线在可靠性强度计算中疲劳极限的均值和标准差的计算,与实验数据比较符合,并对比折线方程的优点加以分析说明,为可靠性设计研究奠定了理论基础。
关键词: 疲劳强度, 疲劳曲线, 可靠性, 设计
Abstract:
Five kinds of fatigue limits stress (σm-σa) diagrams were introduced in this paper, and application characteristics of Good man diagram, Simplified fatigue limit fold curve diagram, Soderberg line diagram ,Биргерparabolaand Gerber parabola curves were analyzed. The calculating values of the standard difference of fatigue limit in reliability intensity of Gerber’s parabola were in good agreed with the testing data. The advantages of the fold curve equations were analyzed in detail, it provided the theoretical supports for the reliability design.
Key words: fatigue strength, fatigue curve, reliability, design
