TNT炸药爆炸冲击波的数值模拟与实验研究

Numerical Simulation and Experimental Research on TNT Explosion Shock Wave

文中基于AUTODYN程序,建立了TNT炸药爆炸场超压分布的仿真模型,进行了数值模拟,并与试验数据进行了对比。结果表明:所建立的计算模型正确,方法可行,数据一致性较好,可以为不同种类爆炸装置外场爆炸试验的安排与设计提供一定的技术支持。

In this paper, the space-time distribution of TNT detonation overpressure field simulation model was built based on the AUTODYN program, numerical simulation was done ＇for the response of the model, and the simulated result was compared with experiment. The results show that the simulation model and the simulation method are proper, and could be used as a reference for field test of different explosive devices.
