doi:10.12382/bgxb.2023.0715

Abstract

Abstract:

For a long time, the dynamic explosive fragment field of warhead has been paid attention to by researchers. The velocity, mass and density of fragment under the action of dynamic explosion have been studied, especially the correlation and the difference between static explosion and dynamic explosion of warhead are one of the hot topics. In order to further discuss the research progress of dynamic fragmentationpower field of blast-fragmentationwarhead, the main factors affecting the velocity field, mass distribution field, and flying direction and density of fragments are expounded by summarizing the research focus in existing relevant literatures, and the problems and difficulties in analyzing the relevant factors in existing literature are pointed out. Among them, the influence of the warhead's own motion condition on the fragmentation power field distribution is analyzed, and the difficulties in the current research in this field are discussed.And then the suggestions for further research work are put forward: develop and perfect the dynamic explosion test technology; perfect the warhead dynamic explosion fragmentation power field theoretical model; and optimize the numerical simulation technology of warhead dynamic explosion process.

Key words: warhead, dynamic explosion, fragment
