运用节点分离法改进传统Lagrange算法模型计算杀伤类弹药破片的爆轰驱动过程.以某榴弹为例,数值模拟了壳体膨胀与破裂的过程,并获得破片的初速与飞散角,并与理论计算对比,两者计算结果相吻合.

In order to study the whole process of detonation drive characteristics of fragment ammunition,the Lagrange model was improved on nodes?tied model. The expanding and fragmentation of the shell of shrapnel were simulated,and initial velocity and scattering angle of fragments were obtained. The results of numerical simulation are in agreement with those of theory.
