高速/超高速碰撞会产生大量破片,并伴随闪光、等离子体等现象.高速碰撞材料受冲击产生射流及破片高温会引起碰撞闪光现象,获得了碰撞等离子体电磁场强度的变化规律.采用数值仿真与理论分析相结合的方法,获得了高速碰撞破片云团分布规律.%Some debris, phenomenon of flash, plasma and etc. Will emerge in the process of high-velocity/hypervelocity impact. High temperature of material shocked by hypervelocity projectile will cause impact flash phenomenon. The change law of electromagnetic intensity is given. Combined with numerical simulation and theoretic analysis, the distribution of debris cloud from high-velocity impact is a-chieved.
