摘要
定位浮标是为满足水下蛙人部队定位要求而设计的。定位浮标的升沉和横摇运动对海水中换能器阵的水声定位精度影响较大 ,而使定位浮标产生这两种振荡的主要激励源是波浪。在不考虑流和风对浮标作用的前提下 ,以规则波作为激励源 ,研究了定位浮标在波浪激励下的两种运动模型 ,然后用计算机对横摇和升沉运动模型进行了仿真 ,最后从运动模型出发提出了减少浮标振幅的有效办法 。
The positioning buoy is designed to localize the underwater frogman army. The pitching and rolling motion of the buoy cause considerably great error to the acoustic positioning precision of underwater transducer array. The exciting source of the two kinds of motions is wave. With the regular wave excitation, the two moving models of the positioning buoy is studied in this paper, without regard to the influence of wind and current. Then computer simulates the two models. Finally, the effective ways to decrease the swing of the poisoning buoy are put forward and it is significant to the design of buoy structure.
