摘要: 对近年来国内外在元件疲劳可靠性估算方法方面所做的研究作了系统的回顾和讨论,按安全余量方程将其分为三类:累积损伤模型、剩余强度模型和疲劳寿命模型,并对这三种模型的特点及局限性作了分析论述,对元件疲劳可靠性分析的发展趋势作了讨论.

Abstract: A detailed review of the evaluation methods of fatigue reliability of structural elementshas been made. Various the models for the fatigue reliability evaluation are classified into threetypes according to the status equations, that is, cumulative damage model, residual strength modeland fatigUe life model. Every model can find its own position in the engineering application, andhas some limits. Some discussions on the further development of the evaluation of fatigue reliabilityare made.
