基于升摇效果分析新型船舶舵减摇潜力

Analysis of the rudder reduction potential of a new type of ship based on the effect of shaking

为探究某新型船舶的舵减摇潜力,将该船舶的实际船体参数引入到船舶运动模型中,通过建立的Matlab仿真平台进行模拟仿真,观察船舶在不考虑海浪等环境干扰情况下,不同摆舵幅度和操舵频率对船舶横摇角的影响。根据横摇角的变化特点设计实验方案,探究该新型船舶在舵速限制下能产生的最大横摇角,分析船舶具备的舵减摇潜力。根据实验可知,通过合理的操舵策略,该船舶能够产生较大的横摇角,具备较好的舵减摇潜力。

In order to explore the rudder reduction potential of a new type of ship,the actual hull parameters of the ship are introduced into the ship motion model,and the simulation is carried out through the established MATLAB simulation platform.Observe the influence of different rudder amplitude and rudder frequency on the ship’s toll angle without considering the environmental disturbances such as waves.According to the variation law of the roll angle,the experimental scheme is designed to explore the maximum roll angle that can be generated under the limitation of hardware conditions,especially the rudder speed condition,and analyze the rudder roll-shake potential of the ship and the feasibility of the rudder roll for the ship.According to the experiment,the ship can generate a large roll angle through a reasonable steering strategy,reflecting its better rudder anti-rolling potential.
