摘要: 利用三参数σ-N曲线方程和等寿命图线,建立了应力幅值、应力均值和疲劳寿命的关系式,即广义σ-N曲面方程。以此作为疲劳寿命估算和疲劳可靠性设计的依据。

关键词: 广义σ-N曲面, 疲劳寿命, 应力幅值, 应力均值

Abstract: A formulae with parameters of stress amplitude, mean stress and fatigue life by using three-parameter σ-N curve and constant life diagram, I. E. , generalized σ-N curved surface equation, is presented. This equation can be used as the principle of fatigue life prediction and fatigue reliability design.

Key words: Fatigue life, Generalized σ-N curved surface, Mean stress, Stress amplitude
