摘要
Abstract
In response to the needs of unmanned mine countermeasures platforms,a novel electromagnetic driving structure is designed to achieve a compact structure,large displacement output,and powerful very low frequency(VLF)radiation capabilities.This structure is characterized by simple design,linearization of input and output,and a high driving force-to-current ratio.Based on the operating principles of the electromagnetic driving structure,an equivalent magnetic circuit model is established and the dynamic model is then established according to the single-degree-of-freedom damped forced vibration model.These models are verified through a finite element simulation model.The simulated electromagnetic force and output displacement are compared with the simulation results based on the equivalent magnetic circuit.The finite element analysis results are in good agreement with the magnetic circuit analysis results,which proves the accuracy of the models.Then,based on the sound radiation model,the output sound source level under 30～200 Hz excitation is calculated.The results show that the output level of the very-low frequency sound source driven by the proposed new electromagnetic driving structure can reach 185 dB at the resonant frequency of 70 Hz,and the output level of the sound source in the frequency band of 30～200 Hz is greater than 145 dB,which can meet the requirements of the very-low frequency high-power output,and the high sound source level output can be realized through modular assembly.It can provide theoretical support for the design of new minesweeping sound source.关键词
