双体船稳性衡准中的横摇角公式

The Formulae of Rolling Angle in Stability Criteria for Catamarans

根据不同船型的６艘双体船在静水和规则波２浪中的模型横摇试验，得到了频率响应曲线、横摇阻尼及船舶自摇周期．讨论了片体间距、舭龙骨面积及排水量－宽度比等参数对双体船横摇角的影响，从而给出了计算双体船横摇角及其周期的公式．

Based on the model rolling tests in smooth water and regular waves for the six catamarans with different hull forms,the frequency response curves,rolling damping and period of ship's natural roll are obtained.The influence of some parameters,such as demi hull space,area of bilge kells and displacement beam ratio,on rolling angle of catamaran is discussed.The formulae of calculating the rolling angle and period of catamaran are given.The effects of catamarans going in irregular waves and defiladed navigation area on both values are also analyzed.
