This paper proposes a method to find a transformation matrix in component mode synthesis. The accurate transformation matrix gives prediction mating with the measured dynamic characteristics of large space structures. In this proposed method, the transformation matrix is obtained from both internal and boundary modes of the components. These modes are measured in modal testing for each substructure attached with additional mass and additional stiffness at substructure interface. The proposed method is applied to a canti-lever beam to confirm that this method can give the dynamic characteristics of the beam. Numerical results show the effectiveness of the proposed method.
