【摘要】 将平面连杆机构的二副杆、三副杆、机架等构件定义为机构二叉树的结点集合,通过定义构件的联接规则,将机构表示为二叉树数据结构,其中树的节点和左、右孩子包含了连接副和构件几何参数等信息。通过对二叉树的后序遍历算法建立了平面连杆机构运动分析方法,采用面向对象技术开发了平面连杆机构运动仿真软件,实现了平面连杆机构的运动分析与仿真,仿真算例表明了该方法的有效性。更多还原

【Abstract】 These components such as two pair bar, three pair bar and racks and so on are defined as node set of planar linkage mecha-nisms binary tree. By defining the connection principle among these components, planar linkage mechanisms can be expressed to be bina-ry tree data structure. The tree nodes and their left or right children include the information of link vice and the components geometric parameters. The method of the calculation of the kinematic pair’s position has established to postorder-traversal algorithm of binary tree used to achieve the kinematic automatic analysis of the planar linkage mechanisms. The object-oriented software technology is used to devolope the software of the mechanism kinematic simulation and realize the planar linkage mechanism kinematic analysis and simulation, Simulation demonstrations proved that the method is effective.更多还原
