Abstract: 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.
