风浪环境下的舰船KT操纵响应模型研究

Research on KT maneuvering response model of ships in wind and wave environment

风浪环境下的舰船操纵性已经成为国内外研究的热点。本文将波浪力添加到KT响应模型的最原始推导过程中,构建一个包含外力附加项的KT操纵响应模型。通过在不同浪高的环境下,对舰船进行Z形试验仿真,分析不同浪高对舰船航行的影响,说明了模型的有效性。通过仿真舰船在不同的航速和舵角的旋回运动,分析风浪环境下不同的操纵情况对舰船操纵运动的影响,对在风浪环境下的舰船操纵有一定参考价值。

Ship maneuverability in wind and wave environment has become a hot topic at home and abroad.In this paper,wave force is added to the original derivation process of the KT response model,and a KT manipulation response model including external force additions is constructed.Through the Z-shaped simulation of the ship in different wave height environments,the influence of different wave heights on the navigation of the ship is analyzed.By simulating the cycle motion of the ship at different speeds and rudder angles,the effect of different maneuvers on the maneuvering motion of the ship under wind and wave environment is analyzed,which has certain reference value for the commander's maneuvering in the wind and wave environment.
