水翼对高速双体船纵向减摇性能影响研究

Hydrodynamic research on longitudinal motion stabilizing hydrofoils of high-speed catamaran

基于水翼在高速双体船上的广泛应用,运用Fluent软件,通过在水翼的攻角、尺寸、安装方式方面进行选型设计,研究水翼与高速双体船之间的相互影响,并且基于静特征数的附体减摇能力分析方法,研究静水中水翼对高速双体船的纵向减摇性能。计算分析结果表明,水翼对高速双体船的纵向运动能起到一定的辅助作用,可以减缓船体的纵摇与升沉。

On the basis of the widespread use of hydrofoils on high-speed catamaran and using Fuent software,this paper layout and design about the angle of attack,the size and installation of hydrofoils of high-speed catamaran,research the effect between hydrofoils and high-speed catamaran,and based on the appendages stabilizing capacity analysis of static characteristic number,to research the stabilizing capacity of hydrofoils for high-speed catamaran in calm water.The calculation results show that hydrofoils can play a role in controlling the longitudinal movement of high-speed catamaran and can slow down hull pitching and heaving.
