摘要/Abstract

摘要：

针对复杂铁磁环境中磁耦合谐振装定系统无法有效工作的问题，基于电磁准静态场基本理论，推导磁耦合谐振装定系统涡流损耗解析表达式，分析该系统能量传输的影响因素。对不同介质环境中的装定系统进行数值模拟和实验研究，研究结果表明：理论分析与数值计算、实验结果趋于一致；涡流损耗为该系统不能正常工作的主要原因，且与系统的谐振频率、介质材料的磁导率和电导率相关；若在钢介质的开槽间隙中加入铁氧体磁环，装定系统20 ms后可以正常工作，能满足引信的装定要求；该结论对磁耦合谐振装定系统在复杂环境下的工程化设计提供参考。

Abstract:

In order to solve the problem of that magnetic resonant coupling setting system can not work effectively in complex ferromagnetic environment, an analytical expression of eddy current losses of magnetic resonant coupling setting system is derived based on the basic theory of the electromagnetic quasi-static field, and the influence factors of the energy transmission system are analyzed. Numerical simulation and experiment study are conducted on the fuze setting system in different environments. The results show that theoretical analysis results are consistent with the numerical calculation and experimental results. The system is not working properly mainly due to eddy current loss, which is related to the resonant frequency of the system, and the permeability and conductivity of dielectric material. When ferrite bead is added in slot gap of steel media, the fuze setting system can work effectively after 20 ms, and can meet the requirement. The conclusion on magnetic resonant coupling setting system is helpful to engineering design in complex environment.
