【摘要】：高空作业车是一种常用的、非常重要的工程机械，随着我国经济的快速发展，高层建筑、电力等行业对高空作业车的需求也越来越多，因此高空作业车设计和制造变得越来越迫切，本论文以自行式曲臂高空作业车为研究对象，应用ADAMS机械系统动力学仿真软件对高空作业车进行仿真分析，并对工作平台调平技术进行了研究，研究成果对高空作业车的设计制造有很重要的参考价值。论文首先介绍了ADAMS软件，并对其理论基础多体动力学作了详细的介绍，对高空作业车工作平台的调平系统进行了研究，，重点对本论文研究高空作业车两种调平方式中的双油缸串联方式进行了验证计算，得出这种调平方式能够满足设计要求。然后运用Solidworks软件对高空作业车进行三维实体建模，将建立好的三维实体模型导入到ADAMS分析软件中进行仿真分析，首先进行仿真获得高空作业车工作平台的工作范围，然后再分工况对高空作业车虚拟样机进行仿真分析，分别获得高空作业车到达三种极限位置工况过程中工作平台的速度曲线、加速度曲线及主臂变幅油缸的受力曲线。各种极限位置工况分别采用顺序动作方式及复合动作方式来进行仿真。将两种动作方式仿真后所获得的速度、加速度及受力曲线进行比较分析，对高空作业车的操作规程提出合理建议，同时通过对各铰点的受力大小及方向进行分析可为后续进行关键零部件的结构设计提供重要依据。
[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.
