Velocity Profile Measurement of a Flyer with Grooving Structure and Its Numerical Simulation
摘要
Abstract
The line-image VISAR was applied in a detonation experiment ,in which a flyer with Zigzag trenches was driven by a divergent detonation wave .The free surface velocity of a 12 mm-long line on the flyer was obtained ,and the velocity distribution on the free surface was also recorded at 1 ,3 ,5μs after the free surface started moving .Finally ,the experimental model was simulated using LS-DYNA program ,the results are in good agree with the experimental results ,w hich prove the potential of Line-Image VISAR in heterogeneous experiment .关键词
