基于能量法的船体分段翻身吊装方案优化设计方法

摘要
分段翻身吊装难度较大,风险较高,目前主要依靠人工经验设计吊装方案,较少有针对分段翻身的优化设计研究。首先对翻身过程中吊绳与相关船体构件的典型干涉问题做出干涉评估并提取干涉约束,结合吊点适应度约束确立若干吊点布置方案。然后以在翻身过程中结构的最大应变能最小为优化目标,得到最优吊点布置方案。最后使用结构分析软件验证最优方案的可靠性。
Hull block turning over lifting is of great difficulty and high risk. At present, the lifting scheme is mainly designed on designers' experience, and there are little researches on the optimization design of the block turning over. Firstly, the interference evaluation of the typical interference between the ropes and hull structures during the turning process is made and the interference constraint is extracted. Several lifting point arrangement schemes are established in combination with the lifting point fitness constraints. Then, with the optimization objective of minimizing the overall strain energy of structure during the process of turning over, the optimal lifting points arrangement scheme is obtained. Finally, structural analysis software is used to verify the reliability of the optimal program.
