平面一维应变电炮加载技术研究

 在分析电炮加载装置放电回路的基础上，探讨了电炮装置的设计原则。根据所提出的设计原则，设计和建立了一门储能14.4 kJ的电炮装置。实验测试结果表明，其性能参数诸如回路电感小于40 nH、放电周期7 μs、飞片平面度小于40 ns、初始电流上升陡度达750 GA/s。与国内外的同类型装置的参数相比较，该电炮装置达到了较高水平，具有较好的性能。在此基础上，提出了获得平面一维应变加载对电炮装置的一般要求。

Study on the Technique of Electric Gun Loading for One Dimensionally Planar Strain

The designing principles are discussed based on the analyses of discharging circuit of electric gun. According to those, an electric gun with the energy of 14.4 kJ is designed and established. The measuring results show that the parameters of the electric gun, for example, the inductance is less than 40 nH, the discharging period is 7 μs, the flatness of the flyer is less than 40 ns, and the rising ratio of the initial current is to 750 GA/s. Compared with the same type of devices at home and abroad, the electric gun is high level and with good performances. Based on the above discussions and analyses, the common requirements are presented for electric gun in order to attain the one dimensionally planar strain.
