摘　　要：针对帽形感应装定中引信接收线圈骨架采用低磁导率高电阻铝合金材料时,引信骨架内将产生反电动势,形成涡流,引起集肤效应,对耦合磁场和回路的谐振特性造成影响,导致系统信号不稳定、装定数据不完整的问题:本文对不同材料在磁场中引起涡流的情况进行了分析,提出了利用有限元方法,通过等效电路模型分析,在涡流影响下建立了引信感应装定能量和信息电压传输通道的电路模型,仿真表明:与铝合金材料相比,采用铬锰硅钢材料制作线圈骨架可将涡流损耗功率减小至1/4,铬锰硅钢具有更高的充电电压、更小的信号偏置和畸变,以及更大的装定范围等优点,实验结果对感应装定骨架选取材料趋势具有一定借鉴意义。In response to the problem of unstable system signal and incomplete setting data caused by the use of low permeability and high resistance aluminum alloy material in the receiver coil skeleton of the cap shaped induction setting,a back electromotive force will be generated inside the fuze skeleton,forming eddy currents,causing skin effect,and affecting the resonance characteristics of the coupled magnetic field and circuit.This article analyzes the situation of eddy currents caused by different materials in the magnetic field,and proposes the use of finite element method and equivalent circuit model analysis to establish a circuit model for the energy and information voltage transmission channel of the induction setting of the fuze under the influence of eddy currents.Simulation shows that compared with aluminum alloy materials,using chromium manganese silicon steel material to make the coil skeleton can reduce the eddy current loss power to 1/4,and chromium manganese silicon steel can reduce the eddy current loss power to a quarter.Steel has higher charging voltage,smaller signal bias and distortion.And with the advantages of a larger installation range,the experimental results have certain reference significance for the trend of selecting materials for induction installation skeletons.
