Transfer Characteristics of Explosion Energy Released by the Charge Confined to Tubes of Different Materials with Lateral Annular Slits
摘要
Abstract
To study the transfer characteristics of explosion energy released by the charge confined to tubes of different materials with lateral annular slits,explosion experiments were conducted involving charges with or without confinement to tubes of four materials.The high speed schlieren photographic system and shock wave overpressure monitoring system were employed to cap-ture the propagation process of shock wave and obtain the distribution law of overpressure respectively,so that the explosion en-ergy transfer law for the charges confined to tubes with lateral annular slits and the influence of tube material on its energy trans-fer characteristics were analyzed.The results showed that after the explosion of the charge confined to tubes with lateral annular slit,both the detonation product and shock waves firstly propagated outward towards the direction with slit,but the propagation towards the opposite direction is relatively delayed.Compared with the symmetric distribution of overpressure generated by a conventional cylindrical charge,the lateral annular slits in tubes could increase the overpressure in the direction with slit,but de-crease that in the opposite direction.The asymmetric distribution of overpressure proved that the charge confined to tubes with lateral annular slits induced Munroe Effect in the slit direction.The hierarchy of Munroe Effect caused by lateral annular slits pre-sented by materials:stainless steel(SS)>polyvinyl chloride(PVC)>fiber reinforced plastic(FRP)>plexiglass(PMMA).关键词
