Performance of a 60 kJ electric gun
摘要: 研制了具有较高驱动能力的100kV/60kJ高速电炮装置。性能实验结果表明,飞片的完整性和飞行平面度均较好,其中平面度优于42ns。该装置可将直径18mm、厚0.15mm的Mylar膜飞片(约53mg)加速到8.1km/s,将直径12mm、厚0.2mm的Mylar膜飞片(约32mg)加速到9.6km/s,表明该装置具有较高的加载能力。本项工作可为开展高应变率加载下的材料动力学响应及其他相关研究提供有效的加载手段。Abstract: A 100 kV/60 kJ electric gun was developed. The electrical character and geometric scale of the load,as well as the experimental setup,were presented. The experimental results indicate that the flyer has good integrality and high flatness. The electric gun can accelerate the 0.15-mm-thick Mylar flyer with the diameter of 18 mm (53 mg) to 8.1 km/s,and the 0.2-mm-thick Mylar flyer with the diameter of 12 mm (32 mg) to 9.6 km/s,respectively. The 60 kJ electric gun has high driving capability and can be used as an effective driver to carry out dynamic response of materials under high strain rates and some other relative investigations.
