摘　　要：文中设计了一款海洋钢桩清除机具,为了得到海洋钢桩清除机具环抱结构合理的设计尺寸,基于环抱结构三维模型,将其设计尺寸通过参数化建模并建立有限元模型,选取环抱结构的质量、最大变形及最大应力为优化目标,通过分析环抱结构设计尺寸的灵敏度,选出对优化目标影响较大的参数,并建立环抱结构多目标优化模型,通过多目标遗传算法进行优化分析并验证。结果表明:优化后环抱结构质量降低了7.82%,最大应力减小了22.54%,环抱结构质量与最大应力均得到较好优化,并得到环抱结构优化后的设计尺寸,从而进一步提高设计参数的合理性,为环抱结构设计加工提供了理论参考。In this article,a marine steel pile removal equipment is designed.In order to work out the reasonable design size of the marine steel pile removal equipment’s surrounding structure,its 3D mechanism is used;its design size is parametrically modeled and the finite-element model is set up.The surrounding structure’s mass,maximum deformation and maximum stress are selected as the optimization objectives.The analysis is conducted on the sensitivity of the surrounding structure’s design size;the parameters that have greater influence on the optimization objectives are selected;the multi-objective optimization model of the surrounding structure is constructed.The multi-objective genetic algorithm is used for optimization and verification.The results show that after optimization the surrounding structure’s mass reduces by 7.82% and its maximum stress reduces by 22.54%.Both its mass and maximum stress are better optimized;the optimal design size is identified,which ensures that the design parameters are rational and provides theoretical support for design and processing of the surrounding structure.
