摘    要:采用高速分幅摄影和激光速度干涉仪(velocity interferometer system for any reflector, VISAR)联合测试技术,对HR-2钢管在爆轰波对碰驱动下的膨胀变形特性进行了研究。实验得到了圆管膨胀变形的过程图像以及圆管特定部位径向膨胀的位移-时间曲线和速度-时间曲线。采用LSDYNA-3D程序对HR-2钢管的膨胀变形过程进行了数值模拟,计算结果与实验结果吻合较好。

关 键 词:爆炸力学    膨胀变形    VISAR测速    HR-2钢管    爆轰波对碰    数值模拟

Abstract:By means of high-speed camera and VISAR interferometer, the expanding characteristics of HR-2 steel tube have been investigated under two head-on colliding detonation waves. The images of tube expanding process were obtained successfully by high-speed camera, and the radial displacement data and radial velocity curve of specific position in HR-2 steel tube were obtained too. In addition, we used LSDYNA-3D program to simulate the progress of the steel tube expansion, the results were co- incident with the experimental results.
Keywords:mechanics of explosion  expansion and deformation  VISAR interferometer  HR-2 steel tube  two head-on colliding detonation waves  numerical simulation
