| 中文摘要: |
| 目的 降低EFI的发火能量，研究非金属飞片与金属飞片在EFI中的应用。方法 采用飞片材料匹配的方法，并选择金属Al与金属Ti，开展金属飞片的设计与制备，得到Al-PI与Ti-PI的金属飞片以及金属飞片-爆炸桥箔metallic flyer，并开展发火摸底试验。结果 在不额外对金属飞片进行绝缘处理的情况下，含有金属飞片的EFI均未发火；对金属飞片进行绝缘处理后，含有金属飞片的EFI均可靠发火。采用光子多普勒测速仪(PDV)进行的飞片速度测试结果表明，在充电电压为1200 V时，Ti-PI金属飞片的速度为3604 m/s，金属飞片-爆炸桥箔一体化换能元速度为2986 m/s。结论 同样的发火电压下，金属飞片-爆炸桥箔一体化换能元的金属飞片速度明显小于绝缘层较厚的金属飞片速度。 |

| Objective To reduce the ignition energy of EFI, and study the application of non-metallic flyer and metallic flyer in EFI. Methods With the metallic flyer matching method, Al and Ti were selected to design and prepare metallic flyer. The Al-PT and Ti-PI metallic flyer and metallic flyer - explosive bridge foil integrated energy conversion element were obtained. Results In the case of no additional insulation treatment for metallic flyer, EFI containing metallic flyer were not ignited. After insulation treatment of metallic flyer, EFI containing metallic flyer were reliably ignited. The results of flyer velocity test with PDV showed that when the charging voltage was 1200V, the speed of Ti-PI metallic flyer was 3604m/s, the speed of material pieces of flyer for bridge was 2986m/s. Conclusion Under the same ignition voltage, the speed of metal flyer with metal flyer and explosive bridge foil integrated energy conversion element is significantly smaller than that of metal flyer with thicker insulation layer. |
