| 摘 要： | 基于流-固耦合有限元法,对工程中经常出现的水平方向高速运动物体砰击水面后的动特性建立了三维砰击模型,并开展了相应的仿真、分析研究,得出了高速运动物体砰击水面后的运动轨迹及其动特性.研究成果对工程中诸如民航飞机水上迫降、空投物体的入水特性分析及高速航行的船舶引擎突然熄火后的动特性研究等工作具有十分重要的现实指导意义.

| Abstract: | Based on the fluid-structure interaction finite elements theory,the paper built up 3-D model of high-level-speed object slamming water,numerical calculating and analyzing,derived the dynamic characteristics after high-speed object slamming water. The result could be significant to study the dynamic characteristics of plane's force-landing,fish torpedo's entering water and high-speed-sailing warship when its engine fails all of a sudden. |
