Abstract
In order to study the effect of rarefaction waves on the response behavior of cylindrical shells with diffe-rent charges,AUTODYN software was used to study the influence of charge type,composite charge layout,and composite charge length on the action range of axial rarefaction wave,the degree of shell fragmentation,and the distribution of axial velocity.Research results indicate that,as the explosive power increases,the area of action of the axial rarefaction wave at the detonation end increases,and the shell in this area becomes more fractured in both axial and radial directions.Increa-sing the charge power at the initiation end does not increase the area affected by axial rarefaction waves,but it will exacer-bate the degree of shell fragmentation and increase fragment velocity in axial rarefaction wave area at the initiation end.The increased power of the non detonation end charge does not affect the fragmentation of the shell,but it will reduce the frag-ment velocity in rarefaction wave influence zone at the detonation end.When the charge length of Comp.B is not within the rarefaction wave influence zone at the detonation end,the shell will fracture at the charge boundary.关键词
