摘　　要：为了研究EFP战斗部结构对其毁伤效应的影响,从侵彻效应和靶后破片效应两个方面进行分析。首先,基于A-T侵彻模型对侵彻深度经验公式进行改进以及数值分析;然后,使用SPH算法,结合AUTODYN仿真软件对EFP战斗部侵彻靶板产生的靶后破片进行仿真分析,并对仿真结果进行正交分析。结果表明:EFP侵彻深度随着EFP速度和长径比的增大而增大;靶后有效破片数量随着EFP速度和EFP直径的增大而增大。In order to study the effect of EFP warhead structure on its destruction effect,analysis were carried out from two aspects of the attack effect and target effect.Firstly,the intrusion depth empirical formula was improved based on the A-T intrusion model and numerical analysis.Then,using the SPH algorithm and AUTODYN simulation software,the target fragments generated by EFP penetration were simulated,and orthogonal analysis of simulation results were conducted.The results show that the EFP intrusion depth increases with the increase of the EFP speed and EFP aspect ratio,the number of effective fragments increases with the increase of EFP speed and EFP diameter.
