摘　　要：文中用 ANSYS/LS—DYNA 非线性动力学有限元分析程序,对一定空腔装药结构的爆轰驱动过程进行了三维数值模拟,得到了破片速度的变化规律。进行了试验,试验结果与数值模拟结果一致性较好。In this papcr.3D numerical simulation on the explosive driving to certain column charge within a hollow is a- chieved by using ANSYS/LS-DYNA program,and the change history of fragment velocity is obtained.Otherwise,a test of the explosive driving on this charge is carried out.and its results and simulation ones are accorded very well.

关 键 词：爆轰驱动 空腔装药 数值模拟 破片速度
