Research Abstract	Dimension reduction method was proposed for a controller design method of flexible multibody systems which used a mathematical expression derived by Absolute Nodal Coordinate Formulation. At first, the dimension reduction method was proposed for a system which consisted of 2-dimensional flexible beam and the method was demonstrated by numerical analysis. Then, the proposed method was extended to the system which consisted of 3-dimensional flexible beam and the method was also demonstrated by numerical analysis. Furthermore, possibility of extension of the proposed method to flexible grid structure was discussed in consideration of the relationship between the structure and 3-dimensional flexible beam. In order to carry out experimental validation of the proposed method, some experimental set up were developed and fundamental function of the set up was checked and some modifications have been attempted in order to improve the performance of the experimental set up.
