摘　　要：以门式液压吊装系统中的主要承重核心——液压爬升机构为研究对象,针对液压爬升机构在承重4.10 MN后,出现不同程度的应力、形变以及几何结构质量较大的问题,在保证结构满足强度要求的情况下,利用SolidWorks软件进行三维建模,并结合ANSYS软件搭建仿真分析平台。以楔块、锚块的角度与楔块、锚块、方钢的厚度为设计变量,以液压爬升机构的最大应力、最大变形和质量为响应,基于响应面利用MOGA(多目标遗传)优化算法,对液压爬升机构进行多目标优化设计。结果表明:优化后的液压爬升机构最大应力降低了26.47%,最大变形降低了26.26%,几何结构质量降低了2.05%。优化后既实现了液压爬升机构的轻量化,又能显著提高液压爬升机构的综合性能,能够快速有效获得液压爬升机构多目标优化的最优解。Taking the hydraulic climbing mechanism,the main load-bearing core of the portal hydraulic lifting system,as the research object,in view of the different degrees of stress,deformation and large mass of the geometric structure of the hydraulic climbing mechanism after bearing 4.10 MN,SolidWorks software was used to carry out 3D modeling under the condition of ensuring that the structure met strength requirements,and a simulation analysis platform was built in combination with ANSYS software.Taking the angle of the wedge and anchor block,the thickness of the wedge,anchor block and square steel as the design variables,the maximum stress,maximum deformation and mass of the hydraulic climbing mechanism as the response,the MOGA optimization algorithm based on the response surface was used to carry out the multi-objective optimization design of the hydraulic climbing mechanism.The results show that the maximum stress of the optimized hydraulic climbing mechanism is reduced by 26.47%,the maximum deformation is reduced by 26.26%,and the quality of the geometric structure is reduced by 2.05%.After optimization,not only lightweight of the hydraulic climbing mechanism is realized,but also the comprehensive performance of the hydraulic climbing mechanism is significantly improved,and the multi-objective optimization optimal solution of the hydraulic climbing mechanism can be quickly and effectively obtained.
