| 摘 要： | 分析零航速减摇鳍的升力模型和力矩模型,探讨正弦运动的鳍产生最大升力和最大转鳍力矩与转鳍速度的关系,经对比发现,同一鳍角幅值转鳍下任一时刻升力的大小与经过该点的角速度的平方成正比。为此,采用通用CFD软件计算方法,验证理论模型的规律,在数值仿真的基础上,拟合升力公式和力矩公式的各个系数,并将实船试验转鳍力矩与仿真结果进行对比,结果表明仿真结果能较好地反映实际转鳍力矩的变化规律。

| Abstract: | The article analyses the Hydrodynamic model of the Fin Stabilizer at Zero Speed and the relationship between the maximum Hydrodynamic force and rotation velocity, the result show that the lift force is Proportional to square of the rotation velocity at any moment under the same amplitude, which is also verified by CFD method and the coefficient of the model is obtained. Furthermore the conformity of the experiment result and the simulation result shows that CFD works well and the conclusion obtained in this article is referentialSfor the control of the Fin Stabilizer at Zero Speed |
