摘要
本文提出了利用损伤力学的非线性疲劳损伤模型,在随机海浪交变荷载作用下,简易海洋平台疲劳可靠性优化设计的遗传算法。
In this paper,a nonlinear fatigue damage model based on damage mechanics and genetic algorithms is used in the optimum fatigue reliability design of a simple offshore platform under stochastic wave load,The reliability of the fatigue damage model and the effectiveness of genetic algorithm which are used in this paper are shown by the results of optimum design.
