Analysis And Parameter Optimization Of Window Water Telescopic Arm Structure Combination Scheme

With the development of the construction industry,the demand for window cleaning machine equipment is gradually increasing.As a new type of mechatronics high-altitude construction equipment with high and new technology content,the window cleaning machine is gradually coming into people’s vision in the wall maintenance and cleaning operation construction.Follow-up is the type of window cleaning machine on the market,the length of the combination form is uneven,so standardized production is very key.This paper takes the telescopic arm of CWGS250 roof track window cleaner as the research object,and puts forward the idea of modular combination.First determine module unit unit module,and then through the c programming language,write a set of complete given a certain value,find all together in a group of number equal to the number of the combination of tasks,through mathematical statistical analysis method is introduced into difference coefficient as evaluation index,such as filter core module from the unit module,modular combination for further research.By using the method of deflection and deflection influence line,the optimal combination scheme of telescopic boom length under the same fully extended length is compared,which provides a foundation for the follow-up research.According to the code of window cleaner and the design code of crane,the mechanical theory analysis of the telescopic arm structure of the window cleaner with the combination of length is carried out,and the modal analysis of the telescopic arm structure of the window cleaner is carried out by using the flexibility method.Using Solid Works 3D design software to build a3 D model of the telescopic arm structure of the window cleaner and import the finite element analysis software.In ANSYS Workbench,Static Structural module is used to analyze the strength and stiffness of the telescopic arm,and the analysis results are compared with the design requirements.The buckling analysis of the telescopic boom structure is carried out to obtain the eigenvalues to judge whether the telescopic boom will be unstable.Modal analysis was also carried out by Modal module to obtain the first 6 order vibration shapes and frequencies of the telescopic boom structure.At the end of this paper,the section size parameters of the telescopic arm structure are optimized for equal stiffness.The strength,stiffness and stability of the optimized telescopic arm structure are checked.The modal characteristics before and after optimization were compared and analyzed.The rated load capacity before and after optimization was compared and analyzed to obtain the optimized telescopic boom performance.Finally,through the idea of this paper,the window cleaner telescopic arm combination scheme is improved,and a commonly used telescopic arm combination scheme table under the fully extended length is summarized.It provides some reference for the subsequent researchers to continue the research on the combination direction of the telescopic arm of the window cleaner.At present,the study of wipe a window machine mostly concentrated in the telescopic boom structure,column structure and motion mechanism research,and so on,to wipe a window machine telescopic jib combination scheme of study or a blank,telescopic arm as the main bearing components,its combination plan of the whole machine working performance will have certain influence,so for the combination of the telescopic arm study is meaningful.
