| 摘 要： | 为有效防护爆炸冲击波及抛掷物等的破坏作用,设计了一种新型装配式双层钢板组合结构体系.采用ALE(arbitrary lagrange-euler)算法对4种TNT药量、2种爆距下结构前方及上方流场规律进行了数值分析,得到了爆炸压力场的分布特点和不同位置的冲击波超压等的变化规律,分析了爆炸冲击波与组合结构的作用过程,并与经验公式及TM5-855-1计算结果进行了比较.分析表明,结构前方爆心水平线上0.3 m范围的超压峰值增大,但药量和爆距对此范围的大小影响不大;结构上方一定范围内的冲击波超压减弱,且随着药量和爆距的增大而减小;药量增大、爆距减小时,结构前上方冲击波超压增强的范围增大.

| Abstract: | Aiming at effective resistance to blast waves and the flying debris,a newly-designed assembled structure with double armor plates was put forward.Rules of explosion field including four kinds of bomb weights and two kinds of distances between the bomb and the assembled structure were studied by numerical simulation with the Arbitrary Lagrangian-Eulerian(ALE) algorithm,and the characteristics of the explosion field and the pressure distribution were obtained.The interaction of the blast waves and the assembl... |
