摘　　要：针对目前履带起重机臂架设计冗余度过剩等问题,以某型履带起重机3 m中间节臂为研究对象,以臂架轻量化为优化目标,建立扭转工况下参数化有限元优化设计模型。在iSIGHT软件中搭建优化流程,进行DOE分析与优化设计研究,仿真结果表明,DOE分析结果与试验结果一致;在保证强度和稳定性的情况下,重量减轻10%。To solve the problem about design redundancy on jib of crawler crane,the optimal design model for a crawler crane 3 m boom insert was built with Ansys parameter design language, in which the lightweight design of jib was optimization objective. The optimization process was created in iSIGHT, and DOE and optimal design was studied. The result shows DOE analysis results agree well with experimental results and the mass of boom insert decreases by 10% in occasion with intensity and stability. satisfying
