摘　　要：某型双尾鳍船尾部流动分离明显,桨盘面伴流的均匀性很差.论文对该船尾部流场进行数值分析,开发、设计了伴流优化装置,通过改善桨盘面伴流均匀性,降低了船体尾部处脉动压力.模型试验验证了该装置的伴流优化效果和减振效果,最终进行了实船安装和应用.One type of twin-skeg vessel has significant separation of streamlines at the stern, and wake on the propeller disk is nonuniform. By numerical analysis of the flow field at the stern, this paper develops a kind of wake optimization device to improve wake uniformity on the propeller disk and reduce ship surface pressure fluctuations on the stern hull surface. The effect of the wake optimization device on the vibration reduction is verified, and installed on a real ship for application.
