摘要: 本文根據機械零件疲勞破壞的基本性質所建立起來的疲勞強度頻率分布與疲勞壽命頻率分布之間的數學關系式,提出了一種疲勞試驗方法,測定在給定疲勞壽命下機械零件的疲勞強度分布類型,從而便于進行機械零件的疲勞強度可靠性分析。而且這種試驗方法具有試驗周期短、成功率高的特點。通過對彈簧的疲勞試驗,證明了這種可靠性疲勞試驗方法是可靠的。Abstract: A new fatigue test called Reliability Fatigue Test Method is advanced in the paper according to the mathematics theory on the relation of frequency distribution between fatigue strength and fatigue lifetime based on the component basic property of fatigue destroy. By means of this method, the component distribution law of fatigue strength can be easily to analyze the fatigue strength reliability of mechanical component. High effeciency of success and the short testing period are some of advantages of this method and a great number of spring parts fatigue test done by author show the feasibility of the method.
