This paper presents an efficient method for dynamic analysis of flexible multibody system. The proposed method is flexible multibody dynamic analysis using deformation modes with reduced degrees of freedom. The deformation modes of a flexible body arc obtained efficiently through finite clement analysis using reduction method of nodal degrees of freedom. The effectiveness of the proposed method IS verified In numerical examples of the high-speed rotating beam and a bump-passing mini-bus
