Research And Development Of Parametric Design Platform For Folding Arm Aerial Work Platform

With the rapid development of China’s economy,infrastructure construction continues to increase,people pay more and more attention to the safety of aerial work,aerial work platform is a very common equipment for aerial protection,the current demand is extremely increased.It is particularly important to realize the systematization and rapidity of the design and development of the aerial working platform.In this thesis,the A45 folding arm type aerial work platform from Jiangsu Dongmai Heavy Industry Co.,Ltd is taken as the research object.With C#as the development language,and combined with the 3D design software Solid Works and the database development software Access,a parametric design platform integrating model building and force analysis is successfully built.The static analysis of the lower arm is carried out by ANSYS APDL,which enriches the practical application significance of the parametric design platform.The specific work contents are as follows::(1)Initial analysis and overall functional design.Firstly,the model provided by Jiangsu Dongmai Heavy Industry Co.,Ltd was analyzed to determine the structural characteristics of each part and the assembly relationship between each other,and the structure size that needs to be parameterized was defined.And the parameter dimension chain was determined according to the assembly relationship between the parts.The functions of the parameterized design platform are generally planned,and the main functional modules are determined to include design module,analysis module and database module.(2)Design module development and database establishment.Select C#as the development language,use C#to SolidWorks secondary development,through the call to SolidWorks API function,realize the folding arm type aerial work platform parts and assembly model reconstruction function,and use C#Winform to establish a friendly man-machine interaction interface.The dimension modification of parts and the model reconstruction of assembly can be realized through the interactive interface.The Access database is established,and the connection between the parameterized design platform and the database is established through C#to realize the data interaction between the database and the parameterized design platform.(3)Development of analysis module.Firstly,the force analysis of the folding arm type aerial working platform is carried out,and the general formula of force calculation is deduced,and the general formula is written into C#program.The dangerous parts and their loads are determined by force calculation,and the calculation results are saved to the database.(4)Database module development.The database module is established,and the data in the database is queried and called through the interactive interface.(5)Static analysis of key parts.By writing the APDL command stream,the statics automatic analysis of key parts of the folding arm platform is realized.
