摘　　要：文章设计了典型多舱结构模型,开展了多舱结构在舱内爆炸作用下的毁伤特性实验,测量了爆炸破片和冲击波载荷,并用高速摄像机记录了爆炸毁伤过程,分析了塑性变形、毁伤模式等结构毁伤特点。结果表明:(1)舱内爆炸作用下结构受爆炸冲击波与破片群联合作用,且舱内爆炸载荷包含明显的准静态压力段;(2)紧贴战斗部的舱壁发生花瓣状破口并将压力泻到相邻舱室,较近结构受冲击波与破片联合作用效果明显;(3)加强筋较好地限制了爆炸破口,但变形梯度较大的地方易产生裂纹;(4)内爆炸作用下普通舱门是舱室结构薄弱环节,须重点关注。Multi-cabin structure was designed under warhead internal blast, and fragments and blast wave loading were measured. At the same time, plastic deformation and failure modes were investigated by highspeed camera. The results show that：（1） Cabins bear combined effect of blast wave, fragments and quasistatic pressure in especial;（2） There would be petalling in the clinging bulkhead, that would vent blast loading to adjacent cabin;（3） Stiffeners enhance strength of bulkheads and decrease blast hole, but those would cause local cracks;（4） Traditional hatch doors are weak parts of cabin under internal blast.
