| 摘 要： | 船舶在系泊或低航速状态下,发动机主机停止工作,船舶失去自控方向能力,船体随波浪左右摇晃,比航行时摇摆更为剧烈。因此,研究零航速减摇鳍非常重要。文章研究零航速时仿生减摇鳍产生升力的模型,其基础为Weis-Fogh机构理论。首先讨论如何旋转才能产生给定的升力。依据吕卡提方程理论,给出模型周期解的存在性和稳定性条件 采用单步Runge-Kutta方法求出模型的数值解,给出保证数值解稳定的条件。

| Abstract: | The engine of ships is laid off at anchor. Ships drift with wave and loss the capacity of controlling navigating direction for self, so the roll is increased and severer than shipping state. It is important to study stabilizer when a ship is at zero speed. In this paper we study the lift model of fin stabilizer that based on potential theory of the Weis-Fogh mechanism when a ship is at zero speed. Firstly, we discussed that Weis-Fogh mechanism how to rotate to generate the lift that has been given. Accordin... |
