摘　　要：支撑架是通过杆件和各种接头、夹具来构建支撑骨架的一种机械装置,它在日常生活及其军事方面都有比较广的应用。针对现有支撑架所能构建的空间小、构建快速性等问题,在研究其它支撑架优点的基础上,综合应用现代设计方法和计算机辅助设计软件,设计一套操作简单、快速、稳定的适用于大型空间搭建的支撑架结构。并利用ANSYS优化设计模块工具,以满足力学条件为约束,以支架的重量最轻为优化目标,对所设计的支撑架的主支撑杆和框架横杆外径和壁厚等七个参数进行了优化分析,最终通过对优化结果分析确定了合理的结构设计参数。The supporting frame is a machine that is broadusing in the daily and military,which constructs supporting frameworks by using varieties of poles and clamps.To the problems consist in existing supporting frames,such as constructing small space only,low speeding,and so on.On bases of the research on the strongpoint of others supporting frame,using modern design methods and software of design augmented by computers generally,a supporting frame with simple operation,high operation speed and steady structure has been designed,which was propitious to the big space constructing.moreover In order to fit the need of weight and reliability,optimal design method and ANSYS optimal design module were used to determine seven design variable of the supporting frame,such as outside diameter and wall thickness of supporting poles and rails,using structural strength conditions as the constraints,the minimal supporting frame weight was taken as the optimization objective.Finally,the design parameters were obtained by analyzing the calculation results.
