From the view of fractal theory and topological graph, an efficient synthesis methodology and a novel analysis approach of three rotational hybrid mechanisms （ HMs ） are proposed. Firstly, the basic concept of the topological graph and the fractal theory are introduced. Secondly, the kinematic characteristic and algorithm are expounded. Thirdly, the model between the hybrid mechanism and fractal theory is established according to the conditions mentioned above. And the procedure of methodology of type synthesis is concluded in detail, meanwhile, the three rotational hybrid mechanism is synthesized. Finally, for analyzing the kinematic characteristic of hybrid mechanisms, the corresponding method is proposed and one of synthesized structure is analyzed by which the validity of the methodology proposed in this paper is proved.
