【摘要】：隨著城市化進(jìn)程的加快,城市電力、建筑、裝飾物等各種養(yǎng)護(hù)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(duì)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(tái)作為一種系列化的工程機(jī)械設(shè)備,廣泛應(yīng)用于船舶、建筑、市政建設(shè)、消防、港口貨運(yùn)等行業(yè)。本文針對(duì)某企業(yè)的GTZZ21型高空作業(yè)平臺(tái),應(yīng)用CAD建模技術(shù)、有限元分析技術(shù)和虛擬樣機(jī)技術(shù),對(duì)平臺(tái)工作機(jī)構(gòu)進(jìn)行參數(shù)化建模與優(yōu)化設(shè)計(jì),提出了一些得到企業(yè)認(rèn)可的結(jié)構(gòu)改進(jìn)建議。本文研究的主要內(nèi)容如下： (1)依據(jù)虛擬樣機(jī)的現(xiàn)代設(shè)計(jì)理念與技術(shù)路線,建立起高空作業(yè)平臺(tái)工作機(jī)構(gòu)的動(dòng)力學(xué)分析模型； (2)利用有限元分析軟件ANSYS對(duì)伸縮臂進(jìn)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(jì)任務(wù)； (3)設(shè)計(jì)實(shí)驗(yàn)方案,采集物理樣機(jī)的基本動(dòng)力學(xué)數(shù)據(jù),以驗(yàn)證高空作業(yè)平臺(tái)工作機(jī)構(gòu)的動(dòng)力學(xué)模型的正確性和合理性； (4)以不同的目標(biāo)函數(shù)建立變幅油缸鉸點(diǎn)的優(yōu)化數(shù)學(xué)模型； (5)改變結(jié)構(gòu)參數(shù)進(jìn)行工作機(jī)構(gòu)的優(yōu)化設(shè)計(jì),通過對(duì)動(dòng)力學(xué)仿真軟件ADAMS輸出的性能指標(biāo)以及有限元分析的結(jié)果進(jìn)行比較,從中找出對(duì)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(xiǎn)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.
