摘　　要：为研究含能破片斜侵彻过程中的装药冲击动态响应,运用ANSYS/LS-DYNA软件对含能破片和铝靶建立有限元模型;通过对不同侵彻速度和着角时的含能破片侵彻铝靶的装药应力、应变及压力进行数值分析,获得含能破片的冲击动态响应规律。结果表明:在斜侵彻过程中,装药头部靠近靶板边缘所承受的压力最高,易使装药产生热点发生爆轰;破片的侵彻速度和着角大小对装药安定性具有一定影响。对含能破片结构设计和装药安定性研究具有一定的参考意义。Abstract： In order to study the dynamic response of energetic role of Energetic Fragments Penetration. Using ANSYS/LS-DYNA analysis techniques to analyze Energetic Fragment Penetrating Target duralumin numerical analysis, analyzing and summarizing the key re- sponse of stress, strain and pressure under different penetration rate and the target angle en- ergetic fragments penetrating aluminum target penetration, dynamic response of energetic fragmentation charge structure is obtained. The results indicate that, in the course of oblique penetrationthe pressure of the charge head near the target plate is the highest. It is easily to make the charge to produce hot spots and detonation. Penetration velocity and the angular size of fragments has some effect on the charge stability. It can be a certain reference for the structure design of Energetic fragments and the charge stability study.
