| 摘 要： | 在目前在船舶与海洋工程结构疲劳可靠性分析中所采用的Ｗｉｒｓｃｈｉｎｇ模型进行了较系统的分析，指出了该模型待改进的主要问题。然后，基于二维概率ＭＩＮＥＲ准则，建立了在变幅载荷谱或随机时间历程载荷谱给定的条件下，对结构构件的疲劳损伤累积进行可靠性分析的新模型。

| Abstract: | Wirsching's model, which is widely employed in fatigue reliability analysis of ship and off shore structure, is analysed systematically- And it is found that Wirsching's model should be modified in several aspects. Then, based on Two-dimensional Probabi1istic Min er's Rule, a new model is established of fatigue reliability analysis of structural component subjected to specified cyclic loading of variable amplitude or stochastic time history. In the end, an example is presented, from which it will be seen that this new model is very con venient and feasible in engineering application. |
