摘要
利用等效电路的分析方法,定量研究声共振探雷模型的谐振机理。在论述声-地震耦合以及声共振探雷集中参数系统模型的基础上,根据机械振动与电路分析的等效原理,建立声共振探雷模型的等效电路系统模型,并用Multisim软件进行仿真分析。结果显示:在给定的参数条件下,仿真得到的共振频率和反共振频率分别为157 Hz和503 Hz,与实验测得的共振频率150 Hz和反共振频率513 Hz基本吻合。表明等效电路分析方法是定量研究声共振探雷模型谐振机理的一个有效手段,Multisim软件为研究地雷和土壤参数条件复杂变化情况下的声波探雷技术提供了一种灵活的工具。
The equivalent circuit analysis method is used to quantitatively research the principle of the acoustic res- onance model for buried mines detection. Based on the acoustic-to-seismic coupling and the acoustic resonance pa- rameter lumped model, the equivalent circuit system of acoustic resonance landmine detection model is developed. The software, Muhisim, is used to analyze the equivalent circuit. The results show that the simulated resonance and anti-resonance frequency is 157 Hz and 503 Hz respectively, which is agreement with the experimentally measured resonance frequency 150 Hz and anti-resonance frequency 513 Hz. Therefore, the equivalent circuit analysis meth- od is proved to be an effective approach to quantitatively research the resonance principle of the acoustic resonance landmine detection model. And the software, Multisim, is a flexible tool to study the acoustic resonance landmine detection model.
