由于小水线面双体船的结构与受力特点比普通单体船更为复杂，因此在结构的优化设计中存在更多的难点。针对小水线面双体船在横向弯曲工况下，存在着大量高应力区域的问题，本文采用自适应模拟退火算法进行优化，获得更合理的设计参数。结果表明，模拟退火算法在双体船结构的设计与优化中有着良好的工程适用性。本研究可为双体船的结构设计与优化提供参考。%The structure and mechanical characteristics of Small Waterplane Area Twin Hull (SWATH) are usually more complicated than ordinary mono-hull ships, therefore there are more difficulties when doing structural optimization and design. When under transverse bending condition, the stress in many regions is very high. This paper utilizes adaptive simulated annealing algorithm to find better design variables. The approach obtained better results and validating the application in engineering practicability. This research provides reference when doing SWATH structural design or structural optimization.
