The invention discloses an active ship bow wing attack angle control method for a test. The method comprises the following steps: acquiring real-time accelerations of a ship bow in two directions of pitching and heaving by using external equipment; angle data needing to be changed are obtained based on the real-time acceleration; a controller on the ship model receives the angle data, converts the angle data into pulse signals and sends the pulse signals to a stepping motor, so that the angle of the hydrofoil is changed. According to the method, preparatory work before testing can be reduced, the same purpose can be achieved under the condition of not additionally adding equipment, required testing accessories are reduced, the damage probability of the accessories is reduced, and the reliability is improved; the requirement for the structure of the first-measurement ship model is low, and meanwhile the requirement for waterproof performance is relatively low.
本发明公开一种试验用主动船舶艏翼攻角控制方法,包括如下:使用外部设备获取船艏的纵摇和垂荡两个方向的实时加速度;基于实时加速度获得需要改变的角度数据;船模上的控制器接受该角度数据并将角度数据换算成脉冲信号发送给步进电机,实现水翼角度的改变。该方法可以减少试验前的准备工作,在不额外增加设备的情况下达到相同目的,减少了所需试验配件,降低了配件的损坏概率提高了可靠性;对首测船模本身结构要求较低,同时对防水要求相对较低。
