【摘要】：高空作業(yè)車是一種常用的、非常重要的工程機械，隨著我國經(jīng)濟的快速發(fā)展，高層建筑、電力等行業(yè)對高空作業(yè)車的需求也越來越多，因此高空作業(yè)車設(shè)計和制造變得越來越迫切，本論文以自行式曲臂高空作業(yè)車為研究對象，應(yīng)用ADAMS機械系統(tǒng)動力學(xué)仿真軟件對高空作業(yè)車進行仿真分析，并對工作平臺調(diào)平技術(shù)進行了研究，研究成果對高空作業(yè)車的設(shè)計制造有很重要的參考價值。 論文首先介紹了ADAMS軟件，并對其理論基礎(chǔ)多體動力學(xué)作了詳細的介紹，對高空作業(yè)車工作平臺的調(diào)平系統(tǒng)進行了研究，，重點對本論文研究高空作業(yè)車兩種調(diào)平方式中的雙油缸串聯(lián)方式進行了驗證計算，得出這種調(diào)平方式能夠滿足設(shè)計要求。然后運用Solidworks軟件對高空作業(yè)車進行三維實體建模，將建立好的三維實體模型導(dǎo)入到ADAMS分析軟件中進行仿真分析，首先進行仿真獲得高空作業(yè)車工作平臺的工作范圍，然后再分工況對高空作業(yè)車虛擬樣機進行仿真分析，分別獲得高空作業(yè)車到達三種極限位置工況過程中工作平臺的速度曲線、加速度曲線及主臂變幅油缸的受力曲線。各種極限位置工況分別采用順序動作方式及復(fù)合動作方式來進行仿真。將兩種動作方式仿真后所獲得的速度、加速度及受力曲線進行比較分析，對高空作業(yè)車的操作規(guī)程提出合理建議，同時通過對各鉸點的受力大小及方向進行分析可為后續(xù)進行關(guān)鍵零部件的結(jié)構(gòu)設(shè)計提供重要依據(jù)。
[Abstract]:Aerial work vehicle is a kind of commonly used and very important construction machinery. With the rapid development of economy in our country, the demand for aerial work car in high-rise building, electric power and other industries is also increasing. Therefore, the design and manufacture of aerial work vehicle becomes more and more urgent. This paper takes the self-propelled curved arm aerial vehicle as the research object, and applies ADAMS mechanical system dynamics simulation software to carry on the simulation analysis to the aerial work vehicle. The leveling technology of work platform is studied, and the research results have important reference value for the design and manufacture of aerial work vehicle. Firstly, the ADAMS software is introduced, and its theoretical basis, multi-body dynamics, is introduced in detail, and the leveling system of the working platform of aerial vehicle is studied. This paper focuses on the verification and calculation of the double oil cylinder series mode in the two kinds of squared adjustment of aerial work vehicle, and draws the conclusion that this kind of adjusting square formula can meet the design requirements. Then the three-dimensional solid modeling of the aerial work vehicle is carried out by using Solidworks software. The established 3D solid model is imported into the ADAMS analysis software for simulation and analysis. Firstly, the working range of the work platform of the aerial work vehicle is obtained by simulation, and then the virtual prototype of the aerial work vehicle is simulated and analyzed under different working conditions. The velocity curves of the platform in the process of reaching the three limit positions of the aerial work vehicle are obtained respectively. The acceleration curve and the stress curve of the main arm variable amplitude cylinder are simulated by the sequential action mode and the compound action mode respectively under various limit position conditions. The velocity obtained by the simulation of the two kinds of action modes is analyzed. The acceleration and stress curves are compared and analyzed, and reasonable suggestions are put forward for the operation rules of the aerial work vehicle. At the same time, the analysis of the force size and direction of each hinge point can provide an important basis for the structural design of the key parts in the future.
