摘要
拓广DAA法用于预报水中一次冲上波对悬浮体的动响应；引入当量能量与当量深度概念，计算有自由水面的水下爆炸迁移气泡多次脉冲动力学特性；数值计算值与实测值作了对比，并给山水中存在圆柱亮时气泡脉动压力的经验公式。
An improved DAA method is developed to predict the dynamic response of suspending shell to underwater shock. The equivalent energy and equivalent depth is introduced to compute the dynamic characteristics of moving and pulsing bubble in water. The numerical computation is compared with the experimental data, and the experimental pressure for mula of pulsing bubble when a cylinder is suspended into water is proposed.
