| 摘 要： | 为了获得可压缩射流冲击下板结构的流固耦合动力学特性,在双渐近法的基础上,针对射流问题的特殊性,将射流冲击问题的边界条件引入到双渐近方法的计算中,形成了种新的适合于工程计算的数值方法.通过研究发现,冲击过程中,板的中心处会产生很大的冲击压力,并探明影响此压力的因素主要有冲击水柱含气量、板的材料、水柱横截面积、水柱头部形状和水柱速度.

| Abstract: | In order to study the characteristic of the fluid-solid coupling dynamics,on the basis of the doubly asymptotic approximation(DAA) method and considering the particularity of the impact problems,this paper introduced the boundary conditions of jet impact problems into the calculation using DAA,thus forming a new numerical method which meets engineering requirements.It was found that a great pressure arose in the centre of the panel in the impact process;in addition,there were five main factors that affected the value of the pressure——the panel material,the gas content,the cross-sectional area,the head shape,and the velocity of the jet. |
