【文章內容簡介】 hod, the wave damping of a strip section is not calculated and the calculated values by any potential flow theories are used as the wave why viscous effects are significant in only roll damping can be explained as follows. Fig. 4 shows the wave ponent of the roll damping for 2D sections calculated by a potential flow theory. Conclusions A simple prediction method of the roll damping of ships is developed on the basis of the Ikeda’s original prediction method which was developed in the same concept as a strip method for calculating ship motions in waves. Using the data of a ship, B/d, Cb， Cm, OG/d, G)， bBK/B, Ibk/Lpp， (pa, the roll damping of a ship can be approximately predicted. Moreover, the limit of application of Ikeda’s prediction method to modern ships that have buttock flow stern is demonstrated by the model experiment. The puter program of the method can be downloaded from the Home Page of Ikeda’s Labo (Acknowledgments This work was supported by the Grantin Aid for Scientific Research of the Japan Society for Promotion of Science (No. 18360415).
