摘　　要：装备战场损伤试验存在实施难度大,试验效率低的问题。为提高试验效能,采用AUTODYN,建立预制破片战斗部有限元仿真模型,模拟了战斗部爆炸及预制破片飞散的过程,仿真结果同实弹试验所采集数据基本吻合,验证了所用模拟方法的有效性。通过分析破片侵彻靶板的损伤规律,建立了球形破片撞击靶板损伤相图,结合破片飞散规律,建立了试验布局参考相图。研究结果表明:预制破片战斗部的爆炸及对装备的打击过程,能够通过数值仿真方式准确的进行模拟,从而大大减少试验费用;所建立的试验布局参考相图,能够为试验布局的设计和优化提供一定的参考。The battlefield damage test was difficult to be carried out,and the efficiency was low.In order to improve the efficiency of the test,a finite element simulation model of prefabricated fragment warhead was established by using AUTODYN.The process of warhead explosion and fragment flying off was simulated.The simulation results were in basic coincidence with the data collected from live-fire test,the validity of the simulation method was verified.The damage phase diagram was established by analyzing the law of fragment penetrating target.Then the fragmentation flying off rules were combined,the phase diagram for test layout reference was established.The results show that numerical simulation method can accurately simulate the explosion process of prefabricated fragment warhead and the attack process to the equipment,thus the test cost could be reduced greatly.The established phase diagram for test layout reference could provide certain references for the design and optimization of test layout.
