摘　　要：提出了基于模态、刚度和强度的岸桥金属结构轻量化设计方法,该方法在保证第一阶整体模态频率不降低、大梁最大变形不增大以及结构最大应力不超过允许范围内的条件下,以HyperStudy和ABAQUS为工具,应用自适应响应面优化方法,进行尺寸优化设计,实现岸桥金属结构轻量化设计。该方法成功应用于某新型岸桥金属结构轻量化设计,最终在模态和刚度基本不变、结构最大应力仍在弹性范围内的情况下,减重14.2吨。A Lightweight method based on the mode frequency,stiffness and strength is provided for quayside container crane metal structure. Based on the mode frequency,stiffness and strength,by using HyperStudy and ABAQUS,lightweight is realized with the optimization arithmetic of adaptive response surface method. A lightweight of a certain new style quayside container crane metal structure with the weight reduction of 14.2T is achieved,at the some time,the mode frequency and stiffness is almost the same as the original design,and the max-stress of the metal strueture is still in elastic scope.
