基于有限元分析的船舶零航速减摇鳍升力机理研究

Lifting mechanism of ship's zero speed fin stabilizer based on finite element analysis

减摇鳍是船舶应用最为广泛的主动式减摇装置,其在船舶高速航行时具有良好的降低横摇的功能。但是,当船舶航行速度较低或者零航速驻停时,减摇鳍的效果会大打折扣,因此,研究船舶零航速时的减摇鳍升力机制,使减摇鳍在船舶零航速下仍具有良好的减摇效果是国内外的研究重点。本文基于有限元分析技术,建立船舶减摇鳍的升力函数模型,研究了船舶零航速时的减摇机理,并在此基础上设计了船舶零航速下的减摇鳍系统。

Fin stabilizer is the most widely used active anti rolling device, which has good roll reduction function when the ship sails at high speed. However, when the ship is sailing at low speed or zero speed parking, the fin effect will be greatly reduced, therefore, the research of ship zero speed fin lift mechanism, the fin stabilizer at zero speed ship still has good antirolling effect, is the focus of research at home and abroad. Based on the finite element analysis technology, the lift function model of ship fin stabilizer is established, and the roll stabilization mechanism of ship at zero speed is studied, and the fin stabilizer system is developed at zero speed.
