摘要

针对传统换能器体积大、功耗高以及现有大尺度爆炸声源经验公式在微型化声源中出现尺度效应不适配问题，本文基于小当量装药特性，通过药量-体积等效计算，设计了圆柱形树脂外壳。利用ANSYS平台建立了微型非金属爆炸声源数值模型，分析了装药量与声源级的定量关系。通过400 m标准基距下的收发合置实验，采用定深悬浮装置进行等深布置，实测数据与数值模拟结果的误差在1~7 dB范围内，验证了该微型爆炸声源设计方法的精确性和可靠性，为优化微型爆炸声源提供了有效技术支撑。

Abstract

To address the undesirable large volume and high power consumption of traditional transducers and the mismatch of scale effects in existing empirical formulas for large-scale explosive sound sources in miniaturized sound sources

a cylindrical resin shell was developed by calculating the charge-volume equivalence

where the shell is characterized by a small equivalent charge. A numerical model of a miniature nonmetallic explosive sound source was established using the ANSYS platform

and the relationship between the charge and the sound source level was quantitively analyzed. Using the 400 m standard base distance in the combined transceiver experiments and the fixed depth suspension device for isobath arrangement

the error in the measured data versus the numerical simulation results was in the range of 1-7 dB

verifying the accuracy and reliability of the design method for microexplosive sound sources. This study provides effective technical support for optimizing microexplosive sound sources.
