摘　　要：混凝土泵车臂架的柔性效应对其零件的强度、末端运动轨迹和液压缸驱动力都产生不可忽略的影响,因此对其进行刚柔耦合分析是必要的。基于有限元分析软件ANSYS和动力学分析软件ADAMS,建立了27m混凝土泵车臂架的多刚体模型和刚柔耦合模型。分析比较了相同工况下多刚体模型和刚柔耦合模型中液压缸的受力,研究了不同速度和阻尼对液压缸驱动力的影响。仿真结果表明,该方法可实现对大型机械臂的刚柔耦合分析,为臂架系统的设计和优化提供理论指导。The boom＇s flexible effect on its parts＇strength, trajectory precision and driving force of the hydraulic cylinder can not be ignored, so it was necessary to do its rigid-flexible coupling analysis. Based on finite element software ANSYS and dynamics sofiware ADAMS, the multi-body model and rigid-flexible coupling model of 27 meter concrete pump truck boom were built. The analysis compared the force of the hydraulic cylinder between the multi-body model and rigid-flexible coupling model under same working conditions, and the impact of different parameters to the driving force of the hydraulic cylinder were studied. The simulation results show that the method is suitable for rigid-flexible coupling analysis of largescale robotic arms, and it can also provide theoretical guidance for the design and optimization of the boom system.
