中文摘要:
      水下等离子体技术已经在诸多领域得到广泛应用,由于其高压脉冲放电的瞬时性和不易观测性,对于该技术电声转换的研究尚未有成熟的理论模型。本文结合水下等离子体声源电声转换装置,较全面地分析了充电回路和放电回路的电特性。在此基础上,给出了系统输入能量、电容器储存能量、负载消耗能量和声能量等概念的定义和计算公式,建立了水下等离子体声源电声转换的模型以及系统总效率模型。最后结合实验装置参数,对水下等离子体声源的电声转换模型进行了验证性计算。研究结果表明本文的电声转换模型是有效的,本文研究成果可为水下等离子体声源系统充放电回路参数的合理设计提供理论参考。
英文摘要:
      Underwater plasma technology has been widely used in many fields, but there is no mature theoretical model for the research of electro-acoustic conversion because of the instantaneity of high-voltage pulse discharge and the difficulty of observation. Based on the analysis of the electric characteristics of charging circuit and discharging circuit, the definitions and calculation formulas of the concepts of system input energy, energy stored in capacitor, energy consumed by load and acoustic energy are given. The electro-acoustic conversion model of underwater plasma sound source and the total efficiency model of the system are established, and finally combined with the parameters of the experimental device. The electro-acoustic conversion model of underwater plasma sound source is verified by calculation, and the results show that the electro-acoustic conversion model is effective. The results of this paper can provide guidance for the reasonable design of the parameters of the charging and discharging circuit of the underwater plasma sound source system.
