摘　　要：为避免船体结构在吊装过程中出现结构失稳、局部变形及屈由破坏等危险状况,提出了基于BLS(BIock Lifting System)吊装软件的船体结构吊装工艺优化设计方案。应用BLS软件对某型散货船艉部分段的吊装过程进行了模拟仿真,校核了多种吊装工况下船体结构的强度、刚度及稳定性。根据校核结果对该艉部分段的吊装方案进行了优化,提出了合理的结构加强措施和吊装改进方案。通过对改进方案重新进行安全性评估得到最优吊装方案,保证了该艉部分段吊装的顺利完成。The optimal design of hull structure lifting technology based on BLS is introduced to avoid the dangerous cases during hull structure lifting, such as instability, local deformation and buckling failure. The lifting process of a bulk carrier stern block is simulated based on BLS, the strength, rigidity and stability of the hull structure in several lifting cases are checked. Based on the check result, the lifting scheme of the block is optimized, the countermeasure of structure strengthening and the scheme of lifting advancement are proposed. The optimum lifting scheme is obtained through the re-evaluation of safety, and the successful completion of the block is ensured.
