| 摘 要： | 基于任意拉格朗日多物质流固耦合算法，对空气采用ALE网格，对炸药采用JWL状态方程，分析爆炸冲击波单独作用及高速子弹与冲击波联合作用下高压气瓶的动态响应。结果表明：在冲击波作用下气瓶应力急剧上升，气瓶出现屈服并发生屈曲，爆心距瓶体越近，气瓶受冲击波的影响越大；联合作用时气瓶变形相对于高速撞击和爆炸波单独作用时有明显的扩大，破坏作用更加明显。

| Abstract: | Based on Arbitrary Lagrangian - Eulerian mufti - material fluid - solid interaction algorithm, ALE mesh for air and JWL state equations for explosive detonation, dynamic response of high pressure gas cylinder subject to sudden impact and blast wave was analyzed. The result shows： when subject to blast wave, the cylinder＇s stress increase sharply, the gas cylinde yield and buckling appears which is more obvious when gas cylinder go closer to the explosion center, when subject to combined effect of sudden impact and blast wave, the gas cylinder deformed terribly, destructive effect became more apparent. |
