Since the accidents involving these “Big Macs” will be devastating. In traditional theory， the ability of withstanding waves will get stronger with the increase of the size of ships. However, we should be fully aware that human beings haven’t fully grasped the factors which affect vessels， strength and safety, in particular, the history of the development of large vessels is not long, and data accumulated is relatively limited, the safety of large vessels hasn39。 目前，業(yè)界密切關(guān)注大型船舶的發(fā)展，同時(shí)船舶的安全。事實(shí)上，造船工業(yè)是相同的。但是，我們應(yīng)該充分認(rèn)識(shí)到，人類還沒有完全掌握船只，強(qiáng)度和安全性因素影響，尤其是大型船舶的發(fā)展，歷史不長，積累的數(shù)據(jù)是相對(duì)有限的，安全的大型船舶被證實(shí)在許多方面仍存在很多未知因素，影響船舶安全。因此，這種 “ 無限大 ” 是相對(duì)的。 結(jié)論 在 池田原預(yù)測(cè)方法的基礎(chǔ)上，這是相同概念作為一個(gè)條法計(jì)算船舶運(yùn)動(dòng)波的方式，并用 船舶 橫搖阻 尼開發(fā) 的 一個(gè)簡單預(yù)測(cè)方法 。最上層 在重心低的情況下，下面那層是在低重心的情況下。 原來的方法也被廣泛使用。 預(yù)測(cè)方法是由姬野 [5]和池田 [6,7]的計(jì)算機(jī)程序?qū)彶椤?所以，一些改進(jìn)的方法以提高準(zhǔn)確行就應(yīng)運(yùn)而生了。 在這些預(yù)測(cè)方法中，池田方法 被廣泛應(yīng)用于許多船舶運(yùn)動(dòng)的計(jì)算機(jī)程序。s method, 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).
