Abstract

Abstract

Using the line-array DPS (Doppler pins system) test technique and a high-speed photoelectric frame camera, we diagnosed the shock wave reflection behavior induced by collision of oblique shock waves in a lead plate, accurately measured the velocity history and captured the bulge evolution images of the collision region. By processing the velocity curves, we obtained such experimental informations as the velocity variation, pressure distribution and plate surface damage. Furthermore, Combining the theory of shock wave reflection, we analyzed and explicated the dynamic behavior of the lead plate’s collision region, concluding that it was Mach reflection that occurred after two oblique shock waves collided.
