摘　　要：利用平面连杆机构组成的多叉树表示,用递归的方法形成平面连杆机构动态树结构,在此基础上建立了树结构节点随机交叉,节点随机变异以及尺度参数随机改变的方法,从而形成新的机构构型。将杆组的动力学分析程序定义为树节点函数,对树结构运用遍历算法,建立了平面连杆机构随机构型时的动力学自动分析方法,从而实现了平面连杆机构在创新设计过程中进行尺度综合并进行即时机构动力学分析。By using multi-branch tree expression of planar linkage structure, a dynamic tree data structure of a planar linkage can be formed by recursion. On this basis, a method, which can cross or mutate the tree nodes and can change the dimensional parameters randomly, is established to form new mechanical structures. Regarded the dynamic analysis program as a function of nodes, then a new way could analyz that thd dynamics of planar linkages expressed by tree data structure automatically, even configurations of linkages are changed randomly, is set up by traversal algorithm of tree structure. It realizes the dimension synthesis and the instant dynamic analysis of during the creative design a planar linkage consequently.
