-
摘要: 基于简易平面对碰加载实验装置,采用DPS测速和传统X光联合诊断技术,实验研究了Sn样品对碰区的动力学行为,给出了包含对碰区主体破碎物质的密度-空间分布数据和样品前表面微喷物质速度、分布宽度的关键信息的总体物理图像。该研究结果为后续爆轰波对碰加载下材料动力学行为实验中诊断技术的选择和解读,以及相关物理规律的认识提供了重要的实验依据。Abstract: Dynamic behaviors of Sn material driven by collision of head-on sliding detonation waves were diagnosticated with pulsed X-ray radiography and DPS.The whole physical picture of the Sn sample, including the physical image of body fragmentation and the width of the free surface ejecta zone, was obtained.The results mark a great progress in the study of dynamic behaviors of metal materials driven by collision of head-on sliding detonation waves.
