| 摘 要： | 为研究密闭腔室内爆炸效应的特性,采用有限元计算方法,对某密闭腔室内中心装药爆炸后流场的产生、传播和壳体动态响应全过程进行了数值研究. 从物理建模、网格划分、求解文件建立和计算结果分析等几个方面进行了较为详细的论述. 计算结果给出了密闭腔室内自由场几个观察点的压力时程曲线、腔室壁面上几个观察点的爆炸载荷压力曲线. 研究结果可以为公共场所等大型建筑物内爆炸效应研究以及结构强度设计提供理论依据.

| Abstract: | In order to study the characteristics of closed chamber explosion effect,the finite element method was utilized to discuss the explosion flow field detonating in center of the closed chamber and the dynamic response of the shell structure. A more detailed work was carried on from the establishment of physical modeling, meshing, the solution file and the analysis of the calculation results. The overpressure-time curves of the gauges in the structure were shown in this paper. The research results can provide the theoretical basis for explosion effect research and structural strength design of public places and other large buildings. |
