【摘要】：隨著城市化進程的加快,城市電力、建筑、裝飾物等各種養(yǎng)護作業(yè)已經(jīng)提到工作日程上來,造船業(yè)、城市林業(yè)、建筑業(yè)等各行業(yè)對高空作業(yè)裝備的需求越來越大、要求也越來越高。高空作業(yè)平臺作為一種系列化的工程機械設(shè)備,廣泛應用于船舶、建筑、市政建設(shè)、消防、港口貨運等行業(yè)。本文針對某企業(yè)的GTZZ21型高空作業(yè)平臺,應用CAD建模技術(shù)、有限元分析技術(shù)和虛擬樣機技術(shù),對平臺工作機構(gòu)進行參數(shù)化建模與優(yōu)化設(shè)計,提出了一些得到企業(yè)認可的結(jié)構(gòu)改進建議。本文研究的主要內(nèi)容如下： (1)依據(jù)虛擬樣機的現(xiàn)代設(shè)計理念與技術(shù)路線,建立起高空作業(yè)平臺工作機構(gòu)的動力學分析模型； (2)利用有限元分析軟件ANSYS對伸縮臂進行有限元分析；有限元分析方法與優(yōu)化方法相結(jié)合,完成結(jié)構(gòu)參數(shù)優(yōu)化設(shè)計任務； (3)設(shè)計實驗方案,采集物理樣機的基本動力學數(shù)據(jù),以驗證高空作業(yè)平臺工作機構(gòu)的動力學模型的正確性和合理性； (4)以不同的目標函數(shù)建立變幅油缸鉸點的優(yōu)化數(shù)學模型； (5)改變結(jié)構(gòu)參數(shù)進行工作機構(gòu)的優(yōu)化設(shè)計,通過對動力學仿真軟件ADAMS輸出的性能指標以及有限元分析的結(jié)果進行比較,從中找出對于在滿足起升力矩的情況下變幅油缸受力最小和伸縮臂的危險截面受力最小的結(jié)構(gòu)參數(shù)最佳組合,得出最終的優(yōu)化結(jié)果。
[Abstract]:With the acceleration of urbanization, urban electric power, buildings, ornaments and other maintenance operations have been mentioned in the work schedule, shipbuilding, urban forestry. As a series of construction machinery, aerial work platform is widely used in ship, construction, municipal construction, fire protection. This paper applies CAD modeling technology, finite element analysis technology and virtual prototyping technology to the GTZZ21 aerial work platform of a certain enterprise. The parameterized modeling and optimization design of the platform working mechanism are carried out, and some suggestions for structural improvement approved by the enterprise are put forward. The main contents of this paper are as follows: 1) according to the modern design concept and technical route of virtual prototyping, the dynamic analysis model of the work mechanism of aerial work platform is established. The finite element analysis software ANSYS is used for the finite element analysis of the telescopic arm, which combines the finite element analysis method with the optimization method to complete the task of structural parameter optimization design. The experimental scheme is designed and the basic dynamic data of the physical prototype are collected to verify the correctness and reasonableness of the dynamic model of the work mechanism of the aerial work platform. 4) establishing the optimal mathematical model of the hinge point of the variable amplitude cylinder with different objective functions; The optimization design of the working mechanism is carried out by changing the structural parameters. The performance index of the dynamic simulation software ADAMS and the results of the finite element analysis are compared. The optimal combination of structural parameters for the minimum stress of the variable amplitude cylinder and the smallest stress on the dangerous section of the telescopic arm is found out, and the final optimization results are obtained.
