【摘要】 利用有限元仿真方法,研究带反声障板的圆柱形接收换能器在非谐振区域的指向性特性,研究发现其水平指向性不仅随轴心到障板的距离有关,还受到障板尺寸的影响,找到指向性的变化规律,并实际制作了带反声泡沫障板的圆柱形换能器,经试验测试,性能与仿真数据吻合良好。更多还原

【Abstract】 In this Paper, a kind of baffled ring directional hydrophones is introduced. On the basis of FEM software, the kind of baffled ring directional transducers were analyzed. The FEM analysis result indicates that the distance and the size affected the direction of the baffled ring transducers. The baffled ring transducers were manufactured. FEM computations agree with the experiment According to the execution, It shows that the direction could be controlled by using the baffled ring techniques.更多还原
