Abstract:
In this paper, with the help of the display dynamic analysis program AUTODYN, a free-field explosion model of the air shock wave generated by the TNT explosion is established, and the EULER method is used to simulate the propagation process of the air shock wave. By analyzing the position, pressure, time and other parameters, comparing with the empirical formula, the accuracy of the numerical simulation is verified, the scope of application of the explosive empirical formula is corrected, and the spatial distribution characteristics of shock wave overpressure under specific working conditions are obtained. Time sensor layout and data analysis lay the foundation.
