摘要:
针对引信电磁感应装定中能量和信息传输通道建模时，忽略弹体中涡流影响，模型不准确的问题，基于分离式变压器能量与信息同步传输理论和涡流理论，提出采用分离式变压器的互感模型耦合涡流回路，描述通道传输特性的方法。通过对传输通道等效电路分析，推导出系统最佳工作条件和涡流损耗功率，并探讨了漏感补偿问题。最后针对两种不同型号引信，实验对比弹体中有无涡流时次级回路输出电压的差异，结果表明该模型能较准确描述装定过程中能量和信息的传输特性。
Abstract:
Currently accepted models of power and information transmission channel in electromagnetic induction fuze setting system are not accurate because the effect of eddy currents in the projectile body is not taken into account.Based on power and information synchronous transmission theory and eddy current theory,this paper puts forward a method of coupling eddy current loop by mutual inductance model of the isolated transformer to describe the channel transmission characteristics.The optimum working conditions and power of eddy current loss are deduced by analyzing the equivalent circuit of the transmission channel,and the problem of leakage compensation is also discussed.Finally,in the experiment aimed at two different fuzes,the secondary output voltages with and without the influence of eddy current in projectile body are also compared.The result shows that this model can accurately describe the characteristics of power and information transmission during setting process.
