摘　　要：为了进一步提高农用挖掘机性能,降低生产成本,以农用挖掘机工作装置为研究对象,在Pro/Engineer中建立了三维模型,将模型导入到ADAMS中建立了挖掘机工作装置的虚拟样机。对其进行了动力学仿真分析,得到了在动臂受力最大的工况下,挖掘机进行转斗挖掘时动臂上4个铰接点受力的变化规律曲线,分析结果为进行动臂的有限元分析提供了依据。In order to make further improvement on the performance of agricultural excavator and lower production cost,this paper took the excavator work device as the research object,established the three-dimensional model by using Pro/Engineer.Then the model was imported into ADAMS to create the virtual prototyping.After making dynamic simulation of the virtual prototyping by using ADAMS,load-time curves of the force of the four hinge point on the arm is obtained under the conditions that excavator works using the bucket hydraulic cylinder and the stress on the arm is biggest.The research has provided the basis for the finite element analysis of the arm.
