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。
First of all, the concept of γ_p_S a_S m_N (confidence level_reliadility_stress amplitude_stress mean) surface is presented. Then the formulas of p_S a_S m_N surface and γ_p_S a_S m_N surface are derived. In addition, fatigue strength distribution function and two_dimensional reliability Miner rule are obtained. At last, a example is given.
