γ-p-Sa-Sm-N Surface Theory and Two-Dimensional Reliability Miner Rule for Fatigue Reliability-Based Design
-
摘要: 首先提出了γ-p-Sa-Sm-N(置信度-可靠度-应力幅值-应力均值-疲劳寿命)曲面概念;然后导出了p-Sa-Sm-N曲面和γ-p-Sa-Sm-N曲面的极大似然估计式;并给出了指定寿命下的疲劳强度概率分布和二维可靠性Miner公式,最后,给出了应用实例。

Abstract: First of all,the concept of γ-p-Sa-Sm-N(confidence level-reliadility-stress amplitude-stress mean)surface is presented.Then the formulas of p-Sa-Sm-N surface and γ-p-Sa-Sm-N surface are derived.In addition,fatigue strength distribution function and two-dimensional reliability Miner rule are obtained.At last,a example is given. -
