基于减摇鳍辅助回转的船舶操纵性能研究

基于MMG分离式建模思想，考虑作用在船体、螺旋桨、舵、鳍的水动力作用，建立双桨双舵船舶四自由度非线性数学运动模型，对某船模在静水中的回转性能进行仿真分析，将单独舵控制的仿真结果与船模试验结果进行了验证和分析，并对比了单独舵控制和舵、鳍联合控制下的回转性能，结果表明鳍参与控制回转时能明显缓解回转过程中的横倾。

Research on ship maneuverability based on combined control of rudder and fin

Based on the MMG separated modeling idea, considering the hydrodynamic effect on the hull, propeller, rudder and fin, a four degree of freedom nonlinear mathematical model of the ship with two propellers and two rudders is established to simulate the turning performance of the ship model in still water. The simulation results of the single rudder control and the ship model test results are verified and analyzed, and the single rudder control and the rudder and fin are compared Finally, the simulation analysis of the roll reduction effect under the action of the fin stabilizer alone and the combined action of the rudder and fin is carried out. The simulation results of the combined control of the rudder and fin show that the fin can significantly decrease the heeling when it participates in the turning.
