锥形结构超声阵列换能器研究

传统外形构造的换能器难以适应水下高速运动.因此,在头部为圆形或椭圆形的普通阵列式换能器基础上,该文设计了一种锥形结构的超声阵列式换能器,其可适用于水下高速航行器.通过有限元仿真确定了阵元尺寸与阵列构造,分析了换能器整体的声场分布,研制换能器样机并测试其电声性能.样机测试结果与仿真结果呈现出较好的一致性,换能器指向性与发...

Research on Ultrasonic Array Transducer with Conical Structure

The transducers with traditional structure are difficult to adapt to underwater high-speed movement. This paper proposes a design scheme of ultrasonic array transducer with conical structure based on the design of ordinary array transducer with circular or elliptical head. The proposed transducer can be suitable for underwater high-speed aircraft. The size and structure of the array element are determined by finite element simulation, the overall sound field distribution of the transducer is analyzed. A prototype of the transducer is developed and its electroacoustic performance is tested. The test results of the prototype are in good agreement with the simulation results. The directivity and emission voltage response of the transducer meet the application requirements. The results show that the structure of the transducer is practical and feasible.
