摘　　要：阐述了横摇阻尼的各种构成成分及估算横摇阻尼的经验公式,分析了某海洋工程辅助船在两种舭部状态下的横摇阻尼,比较选取了横摇性能较好的方案,应用耐波性软件分析了两种舭部方案的横摇频率响应曲线,并试验验证横摇阻尼分析结果。研究表明:优选舭部方案的船舶横摇频率响应曲线同实验结果相当接近。This paper elaborates the composition of roll damping and empirical equations for estimating roll damping; analyzes the roll damping of some offshore supply vessel （OSV） with two kinds of bilge shapes to choose the one with better roll performance through comparison; a seakeeping softvcare is used to analyze the frequency domain roll response curves of the two kinds of bilge shapes, and the results are verified against experiment. This study demonstrates that the frequency domain roll response curve with the optimal bilge shape is very close to the experimental results.
