Structural Optimization And Parametric Design Of Hexagonal Section Synchronous Telescopic ARM Of Building Maintenance Unit

Building Maintenance Unit(BMU)is a large outdoor working equipment for cleaning,maintaining and decorating the exterior wall of high-rise buildings.It can adapt to different exterior wall structures,but the design of modern high-rise buildings is more novel and unique,so the demand for window cleaning machines is increasing and needed.The performance is getting higher and higher,in order to meet the market needs and urban construction,it is necessary to improve the traditional models and design methods.To this end,this paper studies the method of software design and finite element analysis of the hexagonal section synchronous telescopic arm of the BMU from the structural design to the computer aided design.The specific work is as follows:Firstly,according to the standard of "BMU" and the actual use environment of the BMU e,the work and performance requirements of the telescopic arm of the BMU are introduced.The design of the key components on the hexagonal section synchronous telescopic arm and the cylinder are completed.And the selection of floating rollers.According to the overall design scheme of the hexagonal section synchronous telescopic arm,the design rules and installation positions of the remaining components are obtained.Secondly,the structure design of the hexagonal section synchronous telescopic arm series arm is introduced,from the calculation of the structure and component dimensions to the process of building the component model library,database and 2D library.On the Visual Studio platform,the main parameters are input through the C# language implementation program.After reading the database and selecting the calculation,the size of the 3D model is driven in the Solidworks software.After that,the idea and specific work of the hexagonal section synchronous telescopic arm integrated into the BMU auxiliary design system are introduced.Finally,the process of finite element parametric modeling and analysis of hexagonal section synchronous telescopic arm is introduced,including parametric design language APDL,model establishment,load constraint application and solution analysis.Finally,the hexagonal section size optimization is described in detail.The hexagonal cross-section synchronous telescopic arm described in this paper gives full play to the material properties and improves the overall performance of the BMU.The developed BMU auxiliary design software and finite element analysis have greatly improved the design efficiency and accuracy of the BMU,and have broad prospects and application approaches.
