Parametric Design And Finite Element Analysis System Of The Abnormal High Tower Crane Based On ANSYS

For large cooling tower body, chimney, tower bridges of the traffic railway ect.Main construction building with the towering structure, the domestic commonly usedlarge tower cranes in combination with the mode of construction elevator construction,the combined mode has high construction costs, the device is effectively lowerutilization, and security problems are more worried about, you need to layout attached.To the traditional tower crane towering structures existing in such building constructionissues, we carry the structure of the tower machine the innovative design, throughdesign and develop the abnormal high tower crane to meet the constructionrequirements of such structures.In the design process of the abnormal high tower crane, according to the actualsituation, the abnormal high tower crane structure need to multiple modeling, it willcause a lot of repetitive work, the work is considerable. To solve these problems,through research and analysis of the structure of the abnormal high tower crane bycombining VC++and ANSYS APDL parametric language, we develop the finiteelement analysis system dedicated towering alien tower crane. In this paper, the mainresults are as follows:1）Using the APDL language of ANSYS, to achieve the abnormal high towercrane parametric modeling. Prepare the abnormal high tower crane parameterizedcommand stream files to the file system on the command stream to read.2）Using VC++to build the abnormal high tower crane finite element analysissystem. System includes input parameters, finite element modeling of the tower, static analysis, modal analysis, operational interface modules. Users conduct the input andoptions to the frame size parameters of tower, boom, balance arm, sleeve and pingqiao,material properties and section parameters, the system automatically generates thecurrent the abnormal high tower crane APDL command stream file. System backgroundquick start system ANSYS, and invoke the command stream files to generate thecorresponding models. By using of the function of ANSYS conduct parameterized staticanalysis for the abnormal high tower crane, through the relevant input parameters andsettings, which generate static analysis command stream file, the system reads it foranalysis, the stress can be key nodes and strain results.3）Using the dynamic theory of finite element analysis method, through buildingfinite element parametric model of pingqiao of the abnormal high tower crane,we goahead dynamic analysis and take the results as an objective function of optimize thedesign, and using ANSYS optimization algorithm module for flat bridge structureproceed dynamic optimization design, effectively reducing the quality of the abnormalhigh tower crane pingqiao, improving the dynamic performance pingqiao metalstructure, lying the foundation for the whole optimization. Achieving the abnormal hightower crane dynamic analysis, through users setting parameters of dynamic analysis,you can get the natural vibration frequency of the structure and mode shapes.4）Through the example to verify the rationality of the finite element analysissystem of the abnormal high tower crane based on ANSYS/APDL, improve the designefficiency of the analysis.
