片空泡崩溃的冲击力

摘要

片空泡(bulk cavitation)是水下爆炸的特有现象,是目前国内对水面舰艇损伤外力源研究残留的最后一种不甚明了的现象.文中阐述了片空泡崩溃闭合的规律和由此引起的水锤冲击力,明确指出片空泡崩溃是一种潜在的水面舰艇损伤的强外力源.%The bulk cavitation is a unique phenomenon of UNDEX (Underwater Explosion), which is not understood thoroughly at home up to now as the residual last outstanding force source applied to surface ship. In this paper, the law of bulk cavitation collapsing and corresponding pressure of water hammer are expounded. The conclusion is that the bulk cavitation collapsing is a potential and intense damaging source for surface ship.
