机械故障下双桨双舵船操纵运动数值模拟
Numerical simulation for twin-propeller twin-rudder ship maneuvering motion under machinery failure
摘要
Abstract
To study the maneuverability of the twin-propeller twin-rudder ship under machinery failure,a numerical tank was established based on CFD(computational fluid dynamics).Overset grids technique and DFBI(dynamic fluid body interaction)module were used to study the response of the ship during maneuvering motion.Taking DTMB5415M as the research object,the DTMB5415M maneuvering motion under design condition were verified by numerical simulations,and the methods were applied to the numerical simulations for DTMB5415M maneuvering motion under the condition of single propeller failure,single rudder failure and simultaneous failure of propeller and rudder.Results show that the twin-propeller twin-rudder ship maneuverability will deteriorate under machinery failure.The maneuverability of the ship when the single rudder occurs failure is worse than that when the single propeller occurs failure,and the ship maneuverability when the propeller and rudder occurs failure at the opposite side is worse than that when the propeller and rudder occurs failure at the same side.关键词
