碎片云侵蚀效应模化分析

MODELING PENETRATION OF DEBRIS INTO TARGETS

用量纲理论对碎片云破坏效应进行了分析。超高速碰撞产生的碎片云 ,其粒子的速度、大小是影响破坏效应的主要因素。用数值计算和量纲分析方法得到了考虑熔化效应时侵蚀坑深模型律。

Penetration efects of debris are presented by the dimensional method. There exist three factors affecting the penetration of debris into targets, viz. the velocity, size and temperature of each single particle of debris. The penetration modeling law is inferred from numerical simulation and dimensional analysis. It shows that temperature has hardly any effect upon the debris penetration.
