摘　　要：为研究惰性装填物对PELE侵彻混凝土靶板效能影响,利用有限元软件LS-DYNA对不同惰性装填物的PELE侵彻混凝土靶板进行数值模拟。结果表明:与PELE侵彻混凝土靶板相比钢靶的形成破片质量较大、速度较慢;不同装填物对靶板的破坏效能不同;尼龙装填物比橡胶对靶板破坏的面积大,破片数量多。通过实验验证了模拟结果的正确性和可靠性。Researches on the influence of inert fillings on penetration of PELE into concrete targets were carried out. Penetration of PELE with different inert fillings into concrete targets was simulated by LS-DYNA. The results show that the fragments formed by penetration into concrete targets are larger and the velocity is lower than those into steel targets, and the different fillings have different damage efficiency. The damage area and the amount of fragments are larger for nylon filling material than for rubber. Correctness and reliability of the simulation results are verified by experiments.
