| 摘 要： | 分析深水导管架平台方案优选的系统决策问题,给出四种初始设计方案,将基于谱分析方法求得平台的系统名义疲劳可靠性指标作为一项关键约束对平台方案进行优化.根据优化后各方案的最优结构性能参数,综合考虑影响深水导管架平台选型的各种因素,由二元对比方法确定影响因素的权重以及相对隶属度,最终采用三级模糊优选方法对优化后的方案进行模糊优选,并以200 m水深导管架海洋平台作为实例进行分析.结果表明,与传统分析方法相比,先由优化分析得到各初始方案的最优结构性能参数,可以为模糊选型提供准确的定量化指标,减少了模糊因素,更有利于对深水导管架平台设计方案做出合理的评价.

| Abstract: | The complicated system decision problem for design scheme optimization of deep water jacket platform was analyzed.The four initial design schemes with different structure types were proposed.The optimal structure design parameters for each scheme were obtained by optimum design method,in which the nominal fatigue reliability index of structure system obtained by spectral method was taken as a key constraint condition.According to the optimized structural performance parameters,the factors which had effects ... |
