摘要:
为研究爆炸冲击波传播和平面反射现象，运用显式非线性动力有限元软件ANSYS/LS-DYNA对柱形TNT装药在刚性平面上方爆炸产生的冲击波的传播和反射进行了数值模拟，将数值计算结果与试验结果和公式计算值进行了对比，结果表明利用数值模拟能够较好地反映压力场分布情况及爆炸冲击波传播、正反射、正规斜反射到马赫反射的演变过程；研究了装药形状对反射平面测点超压的影响。
Abstract:
In order to investigate the propagation and reflection of blast wave, the shock wave generated by cylindrical TNT charge above rigid plane surface was studied using explicit finite element code ANSYS/LSDYNA. Results of the numerical simulation were compared with experimental datas and empirical equations, and they fit well generally. Changes from blast wave propagation, headon reflection to regular reflection to Mach reflection can be well observed, and the pressure field was obtained; at last, the effects on the peak overpressure due to the shape of explosive charge were also studied.
