摘　　要：通过在挖掘机各个部件上建立局部坐标系,在进行坐标系的坐标转换后能较为简单地求出各关键点的坐标,得到各关键点的运动轨迹,从而有效地解决了传统解三角形法中角度求解易出错和求解繁琐的问题,也有效避免了作图法进行运动分析不易实现变参数分析的问题。Local coordinates systems are set up on each part of an excavator then coordinates of each key point can be derived through coordinates transform so the kinetic trajectory of each key point is obtained.Error-prone and complicated problems in angles-solving with traditional triangle method are effectively solved and problem that variable parameter analysis is difficult to realize in graphic method is also avoided.

关 键 词：挖掘机 工作装置 运动分析 矩阵法
