摘要
Abstract
As an important damage element,the overpressure peak of explosion shock wave directly affects the damage ability of the target.In order to explore the influence of ground type and detonation height on the peak value of explosion shock wave,a TNT near-ground detonation model was established by using ANSYS/AUTODYN software.By comparing the peak value of shock wave overpressure on sand ground and concrete ground under different initiation heights,the following conclusions were obtained:when the detonation height is too low,the reflected wave will affect the explosion source,resulting in a decrease in the peak value of shock wave overpressure.Due to the high wave impedance of concrete,this effect is more obvious on the concrete ground;the peak value of shock wave overpressure below the charge gradually decreases with the increase of detonation height.The influence of ground on charge detonation decreases with the increase of detonation height.When the detonation height increases,the difference of overpressure peak between sand ground and concrete ground decreases.TNT explosion creates a crater on the sand ground,which converge the shock wave.When the observation point is located at the focus of the crater,the measured shock wave overpressure will jump.关键词
