摘　　要：为了研究成型装药双层药型罩射流的形成过程,应用非线性分析软件LS-DYNA对成型装药条件下的双层药型罩射流进行了数值模拟,分析了成型装药双层药型罩在不同罩顶过渡弧半径条件下对射流特性参数的影响。结果表明:成型装药条件下,双层罩不同罩顶过渡弧半径对射流的特性有不同程度的影响,合理调整罩顶过渡弧半径有助于改善射流性能,在工程上有一定的指导意义。To study the double-layer composite liners jet form process, Numerical simulate shaped charge under the conditions of double-layer liners jet by the LS-DYNA software and explore the liners jet characteristic parameters of different radius of the transition arc in the Cover Top.The results showed that： in condition of shaped charge, the double cover of different radius of the transition arc in the Cover Top have different degrees of the characteristics of the jet. A reasonable adjustment the in and out cover can help to improve the performance of. the jet.There have certain guiding significance on the engineering .
