Fundamental Study of a New Method to Estimate Ship Vibration Characteristics : Structural Modification Analysis by Using Dynamic Stiffnes Matrix

Abstract

In this paper, the new method to estimate the ship vibration characteristics in the deep water from results of the experiment in the shallow water is shown. This method is structural modification analysis using dynamic stiffness matrix defined as inverse matrix of transfer matrix. And authors have investigated the advantage of this method in comparison with traditional structural modification analysis using eigenvalue method.
