The invention discloses a control method for autonomously optimizing a ship stern flow field. A propeller is installed in the middle of a ship stern, a steering engine is arranged right behind the propeller, steering oar rotation devices are installed on a ship bottom plate located on the two sides of the propeller, and a water flow sensor is installed on an outer plate of the ship bottom plate located on one side of the propeller. Excitation pieces arranged in a matrix mode are evenly arranged in a ship bottom plate located above and behind a propeller, the excitation pieces monitor excitation force borne by a ship bottom outer plate in the propeller area in real time, and then the excitation force is transmitted back to the control unit in real time. When the ship sails normally, the propellers rotate normally, the ship advances at the set navigational speed under forward thrust, the excitation pieces collect excitation force of a ship bottom plate in real time and transmit the excitation force back to the control unit, the control unit calculates the excitation comprehensive acting force T ', the problem of cavitation of the propellers is solved essentially, vibration of a ship body is reduced, and the ship propulsion efficiency is improved. The propeller life is prolonged.
一种自主优化船舶艉部流场的控制方法,位于船舶艉部船中位置安装有螺旋桨,其正后方为舵机,位于螺旋桨两侧的船底板上安装有舵桨回转装置,位于螺旋桨一旁的船底板的外板处安装有水流传感器;位于螺旋桨上方和后方区域船底板的内部均匀布置有矩阵排列的激振片,激振片实时监测螺旋桨区域船底外板受到的激振力,然后实时回传至控制单元;当船舶在正常航行时,螺旋桨正常转动,船舶受到向前的推力,以设定航速前进,同时激振片实时采集船底板的激振力,回传至控制单元,控制单元计算激振综合作用力T',从本质上解决螺旋桨空泡发生,从而减少船体振动,提高船舶推进效率,延长螺旋桨寿命。
