【摘要】 本文介绍一种基于镶拼圆环制作的大尺寸低频宽带大功率圆柱换能器,换能器工作频带覆盖100Hz～4kHz。首先对圆环换能器的关键性能参数进行了理论分析,然后采用有限元方法仿真分析换能器的电声性能,数据显示该换能器声源级SL可达217dB以上,并据此设计制作了圆柱换能器样机,换能器样机直径540mm,高度约1700mm,重量约240kg,水下正浮力约140kg,同时换能器实现了模块化设计,方便进行组合及调整。对换能器电声性能进行了测试,数据表明该换能器最大声源级可达220.7dB@2kHz。采用2000VA标准功放直推声源级可达到不小于201dB@800Hz～4kHz,最高可达207.6dB,发送电压响应级起伏△Sv为5.9dB@1～4kHz。通过湖上试验及海上试验验证,证明该换能器具有低频宽带大功率声发射、结构简单易布放、易操作的特点,是一款性能优良的低频宽带大功率圆柱形换能器。更多还原

【Abstract】 This paper introduces a large-size low-band high-power cylindrical transducer with working band cover of100 Hz～4 kHz.Firstly,the key performance parameters of the circular transducer are theoretically analyzed,and then the electroacoustic performance of the transducer is simulated by finite element method.Data shows that the transducer sound source level SL can be more than 217 dB.The cylindrical transducer prototype with a diameter of540 mm,of about 1700 kg,has a modular design for easy combination and adjustment.The transducer performance was tested,and the maximum sound source was up to 220.7 dB@2 kHz.The 2000 VA standard power amplifier direct push sound source level can reach no less than 201 dB@800 Hz～4 kHz,up to 207.6 dB,transmission voltage response level fluctuation △ Sv of 5.9 dB@1～4 kHz.Through the lake test and sea test verification,it is proved that the transducer has the characteristics of low-frequency broadband high-power acoustic emission,simple structure and easy operation.It is a low-frequency broadband high-power cylindrical transducer with excellent performance.更多还原
