Abstract

Abstract

The complex terminal ballistic parameters of the warhead will affect the circumferential propagation law of the near ground explosive wave and the damage degree to the target. Studying the propagation law of the near ground explosive wave of the cylindrical charge has important engineering significance to accurately evaluate the damage efficiency. By using AUTODYN-3D software, the near ground explosion of cylindrical charge with different terminal ballistic parameters is simulated and calculated, and the data of shock wave pressure in the front, back and side directions produced by the near ground explosion of cylindrical charge are obtained by modeling in two directions respectively. Thus, the influences of four parameters, namely, the velocity of the battle group, the impact angle, the height of the explosion center and the ratio of the length to diameter of the charge, on the propagation of the shock wave produced by the near ground explosion of the cylindrical charge are studied. The evolution process of the shock wave, the peak pressure and the height of the Mach stem are analyzed. The results show that the height of the explosion center is the main factor affecting the height of the shock wave Mach stem during static explosion, and the impact angle and the length-to-diameter ratio of the charge are the main factors affecting the difference in the height direction of the Mach stem. During dynamic explosion, the height of circumferential Mach stem can be increased, especially in the front; in addition, the peak value of forward shock wave increases linearly with the increase of dynamic detonation velocity. The results of orthogonal optimization show that the dynamic detonation velocity has the largest range to the front peak pressure of the cylindrical charge among the four variables; the impact angle has the largest range to the rear peak pressure; and the height of explosion center has the greatest influence on the height of Mach stem. By studying the circumferential propagation law of the shock wave produced by near ground dynamic explosion of the cylindrical charge, the results show that reasonable adjustment of the charge parameters and the front of the near ground explosion can be used for reference to achieve the maximum damage or reduce the hyper-pressure damage in a certain direction.
