Design of Blast Chamber for Break out Affair and Its Life-Span Evaluation

提出了应付突发事件用爆炸容器的设计方法和使用寿命的评估方法,对JBG系列抗爆球罐在爆炸载荷作用后的残余变形进行了计算,评估了多次重复载荷条件下的使用寿命,残余变形的验证实验结果与计算结果基本一致。

An evaluation method was proposed for the design and the life-span evaluation of blast chamber for break out affair, and the JBG series blast chambers had been designed and built up for resisting 1.0-6.0 kg TNT blast. In order to test the ability of the resistance to blasting, explosion experiment had been done, and the remainder distortions of the shell were measured. According to the method the remainder distortions of the JBG series blast chamber loaded first time by explosion with the allowed maximum explosive mass was calculated and the life-span of use for the shell affected by repeat explosion load was evaluated. The experimental and calculated results of remainder distortion are on the whole the same.
