摘要: 本文从概论和统计学的角度来研究绝对尺寸变化对疲劳尺寸效应的影响。我们不仅研究试件疲劳寿命的差别,更重要的是研究它们各自的寿命分布函数及参数的差别和相互关系,以便达到根据小截面试件寿命分布,估计出真实构件的寿命分布,从而计算出一定可靠度下的寿命。

Abstract: Based on probability and statistics the influenee of absolute size on futigue size effect is studied. The type and parameters of fatigue life distribution function of different size specimen and their relationship have been meticulously analysed so that the machine components' fatigue life could be estimates from fatigue life distribution of specimens with certain reliability.
