| 摘 要： | 为了解决船舶在零航速下减摇的问题,采用一种新的运动控制方法,使减摇鳍的工作不再受航速的限制。根据零航速条件下的特殊运动方式,对减摇鳍在非定常流中的受力情况进行分析,详细讨论了各种流体作用力的产生机理,并给出定量计算公式。结果表明,零航速减摇鳍的升力与它的几何尺寸、旋转角速度和角加速度有关。在此基础上建立了零航速减摇鳍的升力模型,通过仿真结果与实验数据的对比,验证了该模型的正确性。

| Abstract: | In order to eliminate the roll of the ship at zero speed,a new movement control method is adopted to make fin stabilizers work without the effect of speed.The forces on the fin stabilizer are analyzed in non-steady flow based on the special work mode of the zero speed fin stabilizer.The principle of forces produced by non-steady flow is discussed in detail and quantitative formulae are given.The results indicate that the lift of the zero speed fin stabilizer is relauive to its geometrical size,angular velocity and angular acceleration.Then the lift model is set up on the basis of these formulae.The validity of the model is validated by comparing the simulation results with the experimental results. |
