高速/超高速侵彻半无限靶研究进展

Research Progress in Penetration of Projectiles into Semi-infinite Targets at High-velocity/hypervelocity

随着近年来先进钻地弹的发展,侵彻领域的研究重点逐渐由高速侵彻转向高速/超高速侵彻。在超高速侵彻时,侵彻机制发生转变,针对超高速侵彻机制与针对高速侵彻机制的理论解释也有着很大不同。综述了高速/超高速侵彻半无限靶的理论过程,归纳了高速/超高速的临界转变速度,总结了高速侵彻中的空化现象研究现状,并概括了高速/超高速侵彻时混凝土靶的流体本构模型研究。针对当前的研究现状,为今后的相关研究提出了一些建议。

With the development of advanced earth penetrator in recent years,the research focus has gradually changed from high velocity penetration to high velocity/hypervelocity penetration. In the field of hypervelocity penetration,the penetration mechanism has been,and the theoretical explanation of hypervelocity penetration is quite different from that high velocity penetration. The theories about the penetration of projectiles into semi-infinite targets at high velocity/hypervelocity,the critical velocity when the mechanism transition happens,the studies of cavitation caused by high velocity/hypervelocity,and the fluid constitutive models used to describe the response of concrete targets penetrated by high-velocity/hypervelocity projectiles are summarized. Finally,based on the current research status,some research proposals are given for further study.
