FUNDAMENTAL STUDY ON THE NEW METHOD TO ESTIMATE VIBRATION LEVEL ON A SHIP (COMBINATION ANALYSIS OF EXPERIMENTAL MODAL ANALYSIS AND BOUNDARY ELEMENT METHOD)

The fluid-structure coupling analysis method which combines the added mass matrix into the finite element method has been used for many years. However, experimental model analysis has not been used in such an analysis. It is necessary to estimate the vibration level on ships and to examine the validity of the finite element models. In this paper, a new reduced added mass matrix is defined and described, and the validity of the idea is verified by comparing it with Matusuura's theory. A combination analysis of the experimental model analysis and boundary element method is described using the reduced added mass matrix, and the validity of the combination analysis method is verified by comparison with experiments in deep water and shallow water. It is verified that the vibration level on ships in deep water can be estimated using this new method.
