MEFP式战斗部侵彻钢靶的毁伤效应研究

Research on damage effect of penetrating steel target by warhead with MEFP

以MEFP式战斗部为仿真方案,建立仿真模型,通过对仿真过程的模拟来求得的最终形成EFP的各指标参数,以此对靶板进行了毁伤效应数值仿真;并利用具体试验的结果来验证数值模拟结果的正确性,得出了战斗部形成的破片能有效穿透20 m处10 cm钢靶的结论,为后续的研究工作提供了一定的理论和试验依据。

This paper takes the warhead with MEFP as the simulation program, at first, the simulation model is established and then the index parameters of the EFP are got by through the simulation and the numerical simulation of the damage effect of the target is carried out.Its result is verified by the the specific tests.It comes to the conclusion that the projectile of the warhead can penetrate the lOcm depth of the steel target 20m far away and provides the theoretical and experimental basis for the following study.
