| 摘 要： | 聚能爆炸的过程是非常复杂,很难进行精确的解析分析,通过实验手段研究则耗资过于巨大,所以数值分析是有效的近似手段.对于聚能射流对靶板的作用的研究比较少.ALE单元算法是一种比较新的有关流固耦合的算法,因此利用非线性有限元ANSYS/LS-DYNA软件中ALE算法,分别计算两种装药形式(圆锥形装药和球缺形装药)对双层板破坏的动力响应,分析了各计算结果,对比了破口,位移以及应力等变量.得到结论:圆锥形装药在纵向上的破坏要强于球缺形装药,然而球缺形装药能产生更大的破口.

| Abstract: | The process of shaped detonation is very complex,therefore it is hard to get the accurate analytical value.It is very expensive to research it through the experimentation,so the numerical analysis is an effective approximate measure.The effects the jet on the plates were seldom studied.The ALE algorithm about fluid-solid was a new algorithm,so ALE algorithm in the nonlinear finite element software ANSYS/LS-DYNA was used.Two munitions(the charge of taper and lack sphere) were formed by numerical simulation t... |
