稀疏波对不同装药圆柱壳体响应行为的影响OA北大核心CSTPCD
Influence of Rarefaction Waves on the Response Behavior of Cylindrical Shells with Different Charges
为了研究稀疏波对不同装药圆柱壳体响应行为的影响,采用AUTODYN软件研究了不同装药类型、复合装药排布方式及复合装药长度下轴向稀疏波的作用范围、稀疏波对壳体的破碎情况及轴向速度的分布规律.研究结果表明:炸药威力变大,会增加起爆端轴向稀疏波的作用区域,该区域的壳体在轴向上与径向上破碎加剧;增大起爆端装药威力,不增大轴向稀疏波影响的区域,但会加剧起爆端轴向稀疏波区域内的壳体破碎程度及增大破片速度;增大非起爆端装药威力,不影响壳体的破碎程度,但会降低起…查看全部>>
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 rarefactio…查看全部>>
