摘要
研究战场环境下爆炸冲击过程及其对装备部件的毁伤机理,对于武器系统改进和战斗损伤评估具有重要意义。本文利用流固耦合算法进行爆炸冲击模拟,探讨了冲击波形成机理,确定了将爆炸冲击波直接毁伤靶板的方法,以及冲击波的数值定义和加载方法,并利用流固耦合算法进行了爆炸冲击仿真,其方法可以为爆炸冲击与毁伤研究提供一定参考。
Research on explosion impact and its damage mechanism for equipment components under battlefield environment, are important for improving weapons systems and assess battle damage. In this paper, the fluid-structure interaction algorithm is used for explosive shock simulation, shock wave formation mechanism is discussed, the method of blast directly damage target, as well as numerical definition and loading method of the shock waves are defined, the fluid-structure interaction algorithm is used in simulating explosion and shock. The method can provide reference for researching blast shock and its damage.
