摘　　要：为了使塔式起重机自身重量更轻,更易于安装和运输,以此降低生产和运行成本,引入了结构仿生设计思想。以QTZ40塔式起重机臂架结构为研究对象,利用结构仿生设计方法对塔式起重机臂架结构进行了仿生优化设计。经研究、分析发现王莲叶脉的构型符合黄金分割定律,依据相似性评价标准,确定王莲为臂架仿生原型,结合臂架拓扑优化结果和王莲构型规律,确定了臂架的仿生优化设计方案。利用APDL语言建立了臂架的有限元模型,接着利用ANSYS软件对臂架原结构和仿生结构分别进行静力学分析计算,结果显示,仿生模型较原模型减重11.41%,并且在强度、刚度等方面均取得了较好的优化效果。In order to reduce the production and operating costs, make the tower crane itself lighter, easier to install and transport, the structural bionic design is introduced. Take the QTZ40 tower crane boom structure as research object,the structural bionic design method is used to conduct a biomimetic optimal design on tower crane jib structure. The study found that the configuration of King Lotus vein conforms with golden section law,according tosimilarity evaluation criteria, King Lotus is confirmed as the bionic prototype, combined the jib topology optimization resultswith King Lotus configuration law, the bionic optimal designscheme of jib is determined. The finite element model of the boom is established in APDL language, and the results of static analysis on the original and biomimetic structures by using ANSYS software showed that the biomimetic model achievesa 11.41 percent reduction in weight and also good optimization results instrength, stiffness compared with the original model.
