EXPERIMENTAL MEASUREMENTS AND 2D NUMERICAL SIMULATIONS OF THE MOTION OF FLYERS DRIVEN BY SLAB CHARGE INITIATED AT CENTRED POINT

本文报导点引爆圆板装药驱动飞板的实验及二维数值模拟研究结果。实验测定了有机玻璃、铝、钢和铜四种飞板在爆轰产物驱动下的碰靶时间及碰靶波形,并将二维数值模拟结果与测量结果进行了比较,二者符合较好。文中还就数值模拟中存在的一些问题进行了简要分析、讨论。

The results of experimental measurements and 2D numerical simulations of the motion of flyers driven by slab charge initiated at centred point are reported in this paper. The time and the front surface shape of flyers impacting on targets were measured experimentally and simulated by 2D numerical code for four different flyers of PMMA, Aluminum,steel and Brass The numerical simulation results agree well with the experimental data. Some techniques on numerical simulation are also mentioned in the paper.
