摘　　要：扒渣工作装置(扒臂)是扒渣机的主要组成部分,扒渣机作业效率依赖于扒臂的工作效率。在对扒臂进行运动轨迹分析基础上,基于牛顿-欧拉法对扒渣工作装置进行动力学建模,并利用MATLAB对模型分析计算,得出机构末端(斗齿尖)的速度、力曲线,分析出油缸的驱动参数。以广义惯性椭球理论对整个作业空间的动力学性能进行分析评价,为扒渣机的结构设计和运动控制提供数据支持。The main components of slag-raking machine is operating arm,its working efficiency is the most important parameters for slag-raking machine.On the motion trajectory of operating arm,dynamic modeling for operating arm was did by new-euler approachan and dynamic modeling was calculated in matlab.The parameters of speed and force for dipper teeth could be obtained,and the driving parameters of hydraulic cylinder could be obtained too.The performance of dynamic for operating arm was evaluated on the theory of generalized inetia tensor ellipsoid.The conclusion was used to design structure and control motion.
