There are several approaches to vibration analysis by Transfer Function Synthesis Method and Transfer Function Dividing Method. Because they assume the joints between substructures are pins, it is difficult to analyze an actual structure with joints which transfer moments. This paper proposes a Transfer Function Synthesis Method which considers moment transfer through joints. To improve the dynamic characteristics of machines of structures, it is neces5ary to change some of their parts. If we know the dynamic stiffness of the original total structure, the substrcture to change, the structure to be changed, and the joint's influences, the characteristics of a new structure may be found by adding them. A total structure is made by 2 bars with 2 bolt joints (dia 3mm, length 40mm) ; the above-mentioned method is applied to it and the results are compared with experimental results. Some good agreements are observed. The FEM substructure is also useful for new substructure.
