| 摘 要： | 快堆的主容器内存在着自由表面流体,当发生长周期地震时,该流体的晃动会冲击到容器壁,对反应堆造成威胁.本文采用ADINA软件建立快堆主容器的三维有限元模型,模拟了正弦三波激励下液面晃动对容器壁的冲击现象,得到的冲击压力为容器结构完整性分析提供了载荷,验证了运用ADINA软件对自由表面流动进行分析的可行性以及在处理流固耦合问题上的优越性.

| Abstract: | There is the free surface in the main vessel of fast reactor.When long period earthquakes happen,the fluid will impact the wall of vessel and make the reactor dangerous.The 3D finite element model of the main vessel is constructed using ADINA,and the phenomenon of sloshing response to the free surface in the main vessel of fast reactor excited by 3 sine waves is simulated.The impact pressure from this research has provided important loadings for the integrality analysis of the main vessel.The feasibility of... |
