    Abstract
  • An evaluation method was proposed for the design and the life-span of use 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 remainded distortions of the shell were measured. According to the method the remainded 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 remainded distortion were on the whole the same.
