摘　　要：文中以1000 t单臂架门座起重机结构为研究对象,提出对臂架和人字架采用Q690C材质,并将门架形式由传统的8撑杆+下部回转组合的形式改为用新型端梁+横梁+圆筒体的3件组合形式,以达到轻量化设计的新思路。根据相关规范要求,文中结合有限元方法,用Ansys软件建立了1000 t单臂架门座起重机结构的有限元模型,通过仿真模型计算分析了该门座起重机在多种工况下的应力分布情况,确定了主结构的截面参数,为结构设计和优化提供了依据,也为提高设计效率提供了方法。Taking a 1,000-ton single-arm gantry crane as the research object,an optimal design is proposed.Specifically,the jib and herringbone are suggested to be made from Q690C material.Additionally,the gantry structure is redesigned from the traditional combination of eight struts and lower rotation to a new configuration comprising an end beam,cross beam,and cylinder.This innovative approach aims to achieve lightweight design while maintaining structural integrity.In accordance with relevant code requirements and leveraging the finite element method,a finite element model of the 1,000-ton single-arm gantry crane structure was established using Ansys software to calculate the stress distribution of the crane under various working conditions and determines the section parameters of the main structural components.The study provides solid basis for structural design and optimization,and offers a method to enhance design efficiency.
