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
With the rapid development of China’s economy, aerial working platform as mon
and very important engineering machinery is more and more demanded in the industries of
high-rise buildings and electric power, which makes designing and manufacturing of aerial
working platform to be of more and more pressing issues. Based on self-propelled and
folding-arm type aerial working platform, this thesis studies simulation analysis of aerial
working platform via ADAMS machinery system dynamic simulation software and discusses
aerial working platform leveling technology. The study results e very significant
references for the designing and manufacturing of aerial working platform.
Firstly, ADAMS software and its theoretical basis called multi-body dynamics are
introduced in details. Secondly, leveling system of the aerial working platform is discussed,
which emphasizes the validation and calculation of dual-cylinder series system in the two
ways of aerial working platform leveling to certify that this leveling method can de
