摘 要:为研究活性横向效应增强弹(Penetrator with Enhanced Lateral Effect, PELE)对钢筋混凝土靶的冲击爆燃毁伤效应,采用有限元分析软件对活性PELE毁伤钢筋混凝土靶作用行为进行数值仿真研究。基于点火增长模型,建立可描述活性芯体冲击反应过程的数值仿真模型,并根据弹道驱动试验结果对数值仿真模型进行有效性校验,计算结果与试验结果吻合较好。在此基础上开展不同冲击速度和壳体厚度条件下活性PELE对钢筋混凝土靶的毁伤特性研究。研究结果表明,随着冲击速度的提高和壳体厚度的增加,混凝土靶通孔尺寸呈先增大后减小的趋势,而对于崩落尺寸,弹丸的冲击速度则是主要影响因素。The impact/deflagration-induced damage effect of reactive penetrator with enhanced lateral effect(PELE)on reinforced concrete target is studied by using the finite element analysis software to simulate the behaviors of PELE acting on a reinforced concrete target.A numerical simulation model for describing the impact response process of the reactive materials core is established based on the ignition growth model.The validity of the numerical simulation model is verified according to the test results of a ballistic gun.The calculated results of the simulation model are in good agreement with the test results.On this basis,the damage characteristics of active PELEs against the reinforced concrete targets under the conditions of different impact velocities and shell thicknesses are studied.The results show that the through-hole size of reinforced concrete target increases at first and then decreases with the increase in impact velocity and shell thickness,while for the collapse size,the impact velocity of projectile is the main influencing factor.
