Abstract
To quantitatively study the air blast wave field characteristics of the explosive charge moving at different velocities,we carried out simulations using AUTODYN software.The simulation results show that the charge velocity exerts great influence on the time-space distribution of the blast wave field.At the initial stage of the explosion,the moving speed and the displacement of the blast wave field are positively correlated with the charge velocity.The space distribution of the dynamic blast wave is non-uniform,the relation of the blast wave's overpressure with the angle is approximately cosine function,and the variation amplitude increases along with the increase of charge velocity.Also,we analyzed the correlation between the static and the dynamic blasting shockwave field,and established the engineering calculation model for the dynamic blasting shock wave overpressure.The modeling results agree well with the dynamic experimental and simulation results.关键词
