摘要
利用动力分析有限元程序LS-DYNA3D,对战斗部装药在建筑物内部爆炸载荷作用下的动力响应进行了数值模拟,并与经验公式的计算结果进行了对比,结果表明数值模拟结果与经验公式计算结果相一致,证明了建立的有限元模型的可行性,可为战斗部的设计及目标防护设计提供依据。
The finite element program LS-DYNA3D was used to numerically simulate the dynamic response of damage effect for explosion in building. The result obtained by numerical simulation and that obtained by empirical formula calculation were compared and it is found that the both are consistent. The feasibility of the built finite element is proved, and it can be referred to warhead design and target protection design.
