摘要
(清华大学核能技术研究院,北京,100084) 运用MSC.DYTRAN软件分析了飞机撞击反应堆安全壳的动力学问题,给出了混凝土的变形图和撞击物的速度变化曲线,比较了选用不同材料模式的计算结果,并与经验公式的结果进行了对比。选用混凝土的帽形材料模型得到结果略低于经验公式的结果。
Dynamic character of reactor containment subjected to aircraft impact loading is analyzed with MSC.DYTRAN program. The displacement of concrete and velocity curve of airplane is obtained. The results of the different material model are compared with empirical formula. It is concluded that reasonable result can be obtained using cap model for concrete.
