Abstract
In order to study the influence of traction velocity of cylindrical charge on the overpressure of shock wave,dynamic analysis software AUTODYN was used to simulate the dynamic explosion process of the cylinder charge in water,the influence of the traction velocity and the length-diameter ratio of the cylindrical charge on the shock wave overpressure field was obtained.It shows that under the influence of traction velocity,the difference of the blast wave overpressure of different length-diameter ratio on the different azimuth angleθis more obvious than the static explosion.When the traction velocity is 0 m/s,the axial pressure (azimuth angleθis 0°)caused by the explosion of the small diameter ratio is relatively high,the peak value of radial overpressure is lower,while the axial direction (azimuthθis 0°) of the charge with large diameter ratio is low,and the peak of radial overpressure is high.When the traction velocity increased from 0 m/s to 200 m/s,the maximum overpressure peaks of the axial and ra-dial axes are increased by 7.8% and 7% respectively compared with the static.关键词
