摘    要:为了研究离散多层爆炸容器的动力响应和破坏特性,制造了尺寸和材料相同但钢带缠绕倾角不同的三台离散多层试验容器,并进行了一系列大药量的中心加载试验,测量了典型位置的应变。结果表明中心装药时三台试验容器的破坏都在爆心截面处,钢带缠绕倾角较小的容器能够承受更大炸药量的爆炸作用,容器具有较好的抗内爆炸性能。

关 键 词:爆炸力学    动力响应    爆炸载荷    离散多层容器    压力容器

Abstract:A discrete multilayered explosion containment vessel(DMECV) mainly consists of covers,inner shell and steel ribbon layers crossly helically wound on the inner shell.Three DMECV with the same materials and dimensions except helical winding angle were fabricated and used to investigate dynamic response and fracture characteristics of DMECV subjected to internal blast loads at the center.All tested DMECV are damaged in the cylindrical portion near the explosion center.The DMECV with smaller ribbon winding angle has better capacity for withstanding internal explosion.Results also show that DMECV have excellent explosion resistance.
Keywords:mechanics of explosion  dynamic response  blast loading  discrete multilayered explosioncontainment vessel  pressure vessel
