摘要
攻击武器战斗部爆炸威力的仿真计算是设施、装备防护研究工作者和武备使用者所关心的问题。本文采用大型通用有限元程序MSC/Dytran,使用有限体积法及流固藕合技术,计算了某型30mm口径燃烧榴弹爆炸时的破片威力。同时,针对该问题,使用经验公式进行计算,并将计算结果与仿真结果进行比较、分析,仿真结果与经验公式有较好的一致。
The explosive power simulation of weapon' s warhead is a matter of concern for the structural protectors.In this paper,the general coupling of finite volume method and ROE technology and the large commercial finite element code MSC/Dytran have been used to calculate the power caused by fragments of certain 30mm- caliber shrapnel.Meanwhile,results have been obtained by experiential equations.The results obtained through the two different ways agree with each other.
