摘　　要：为了优化卷绕型带状脉冲形成线的输出特性,设计了两种新型的绕制方法,并对制作的带状线进行了模拟研究。结果表明:不同的绕制方法会在一定程度上影响卷绕型带状线内部导体间的耦合特性,进而影响其内部的电磁场分布。设计带状线参数为:延时100ns,阻抗1.1Ω,充电电压25kV,分别研制了不同绕制方法下的卷绕型带状脉冲形成线,并进行了实验研究。结果表明:设计的双平板绕法与传统的三平板绕法制作的带状线输出特性相似;地线间隔绕法制作的带状线上,负载上输出波形得到了明显的改善。实验结果与模拟结果基本一致。因此,根据不同的应用情况,合理选择卷绕型带状脉冲形成线的绕制方法可以改善输出特性、节约成本。Two kinds of convolution methods were designed to optimize the output characteristics of rolled strip pulse forming line（RSPFL）.Simulation results show that convolution methods influence the electromagnetic field distribution in the RSPFL,especially the coupling characteristics between conductors.Along with the tranditional convolution method,three kinds of RSPFLs were made accordingly.The results show that different convolution methods do affect the waveform on the load when the time-lapse is 100 ns,impedance is 1.1 Ω,and charge voltage is 25 kV.The two-plate structure has similar output characteristics with the tranditional three-plate one.The simulation results agree with the experimental ones very well.Thus a suitable convolution method could improve the output characteristics of RSPFL obviously and cut cost.
