混凝土泵车臂架静态分析及动力学仿真

Static Analysis and Dynamic Simulation of Concrete Pump Truck Boom

混凝土泵车作为一种高效混凝土浇筑设备,经常在各种复杂的现场情况下工作,因此要求臂架系统具有较高的整体刚度、强度,并具有良好的工作适应性和可靠性,这就给混凝土泵车的臂架设计提出了严格的要求。使用ANSYS对臂架系统三维模型进行有限元分析,从而得出臂架系统的应力和应变情况。使用ADAMS建立混凝土泵车各相邻节臂之间铰点系统的仿真模型,分析臂架在不同位置时节臂加速度和受力的变化规律,为臂架结构参数的确定提供边界条件和决策依据。

Concrete pump truck,a highly-efficient concrete pouring equipment,often works in a variety of complex conditions. Therefore,the concrete pump truck should have a boom system with a high degree of overall stiffness, strength, reliability and adaptability to work, which are strict requirements for the design of the boom system. In this paper,the finite element analysis of the threedimensional model of the boom system is carried out by ANSYS,and the stress and the strain of the boom system are obtained. Then,ADAMS is used to establish the simulation model of hinge system between adjacent arms of concrete pump truck. The change rule of acceleration and stress of the arms are also analyzed when the booms are in different positions. The result provides the boundaryconditions and decision-making basis for the parameters of boom structure.
