船舶零航速减摇鳍升力测量研究

Study on lift measurement of ship fins stabilizer at zero forward speed

船舶零航速减摇鳍是指在来流速度为零的流场中依靠鳍的主动摆动产生升力,以对抗海浪的作用力,从而减小船舶摇摆的减摇技术。在升力测量中,将升力控制引入零航速减摇技术中,根据实船安装环境几个耦合因素的影响,针对零航速减摇鳍,设计了零航速减摇鳍升力传感器;通过反馈信号合成算法,合成的升力信号有足够的精度,证明所设计系统能够满足船舶零航速减摇的要求。

Ship fins stabilizer is a kind of anti rolling ship technique that could produce lift with initiative swing of fins at zero forward speed, and the lift could counteract the rolling forces of ocean waves. The lift control concept is introduced into the anti rolling ship at zero speed. For the zero speed fins stabilizer,the lift sensor is designed that take into account the factor of fixing of the sensor in the actual ship and the coupling factor;the integrated lift signal has sufficient precision by synthesizing arithmetic of feedback signal, and the designed measurement system of lift could satisfied the requirement of anti rolling ship at zero forward speed.
