摘　　要：为综合得到含复合铰链的八杆机构所有构型,提出了一种基于杆组邻接矩阵的构型综合方法。首先,根据机构构件数目,分析机构所有可能的装配组合,并且构造杆组邻接矩阵对角元素。其次,由于机构中复铰类型及个数情况均有不同,将机构分为复铰因子v=1-4的不同类型,根据不同类型,将各级Assur杆组依次连接到前各元素的构件或者运动副上,形成多副杆或者复铰,同时逐步构造杆组邻接矩阵中其余元素,并同步辨识同构体。最后,直至将所有杆组全部连接完成,获得含复铰的八杆机构全部构型。应用该方法,求出了含各类型复铰及不同复铰因子的八杆机构共681种。In order to obtain all structures of eight-bar mechanism,a type synthesis method for eight-bar one degree of freedom（ Do F） multiple-joint mechanism is proposed based on the group adjacent matrix. Firstly,according to the number of bars and degree of freedom,we analyze all combination of the Assur groups and construct the diagonal elements of group adjacent matrix. Then,for difference in the numbers and types of multiple-joint,the mechanisms are divided into different types with multiple-joint factor（ v） of 1 - 4,and the Assur groups are connected to former linkages or joints to form the multiple pair linkage or multiple-joint. Meanwhile the other elements of the group adjacent matrix are progressively constructed and the isomorphism is identified in synchronism. Finally,all the groups are connected and all types of eight-bars multiple-joint mechanisms are obtained. The present structural design method generates a total of 681 kinds of structural forms for eight-bar one-Do F multiple-joint.
