Precise Control Technique for Flatness of Flyer under Explosive Loading

National Key Laboratory of Shock Wave and Detonation Physics, Institute of Fluid Physics, CAEP, Mianyang 621999, China

摘要

摘要: 以有效装药长度模型为基础，通过沿径向向中心方向逐渐增加低阻抗材料缓冲层厚度的方法，实现了飞片击靶波形的精密控制。实验结果显示，在80 mm范围内飞片击靶波形差小于80 ns，一维平面冲击波有效使用范围由原来的40 mm提升至80 mm，可以布置实验样品的面积提高了约3倍。以此爆轰加载装置为平台，测量了钽的冲击Hugoniot物态方程参数和无氧铜的高压声速数据，实验结果与以往的实验数据吻合得很好，表明该技术可用于材料多物理量联合测量的精密物理实验研究。

Abstract: Based on the effective charge length model, the flyer flatness under explosive loading is improved by increasing the thickness of the attenuation plate gradually along radial orientation. The experimental results show that the difference of shock wave front arrival time is less than 80 ns within a range of 80 mm. The area, which is suitable for setting multiple samples in shock compression experiments, is enlarged by about four times than before. Measurements on shock Hugoniot data of tantalum and sound velocities of copper were performed by using the developed explosive loading technique. The obtained experimental data are all in excellent agreement with previously published results, showing that the new explosive loading technique can be used for multi-physics parameter measurements in shock compression experiments.
