摘要：
When the magnetic resonance coupling wireless setting system of fuze is located in cylindrical metal environment, the setting coil will produce the scattering field impedance due to the influence of the metal environment, resulting in change of the working parameters of the system. In order to study this problem, a calculation model of the coil scattering field impedance is established, and the change rules of equivalent parameters of coil with frequency, spacing and metal material are researched experimentally. The theoretical analysis and experimental results show that the proposed model is correct, and the theoretically calculated results are consistent with the experimental results. The equivalent resistance of the coil increases and the inductance decreases due to the existence of metal objects. In addition, the increase in resistance caused by ferromagnetic materials is more than that caused by non-ferromagnetic metal materials, while the decrease in inductance is less. After the scattering field impedance caused by metal environment is calculated by using the proposed model, the setting system can be returned to the resonance state by adjusting the capacitance parameters of the circuit. The proposed model can be used for the quantitative calculation of setting coil parameters under the influence of metal environment. © 2018, Editorial Board of Acta Armamentarii. All right reserved.
