摘要
贮液容器的液面晃动问题是反应堆工程中的重要问题之一。MSC-DYTRAN有限元程序能较好地模拟贮液容器的液面晃动问题。本文以反应堆压力容器和研究堆水池为研究对象,利用DYTRAN有限元程序分别对圆柱形和矩形贮液容器的液面晃动进行了分析。结果表明:在频率大于1Hz的激励下,液面晃动幅值较小;在较低频率激振下,液面晃动幅值较大;在矩形容积的液面晃动中还存在液体飞溅现象。
The study of liquid sloshing with a free surface in a conta iner is essential for nuclear reactor engineering.MSC-DYTRAN,a CAE(Computer-Aided Engineering)software of MSC Corporation,can simulate the sloshing process.The study gives two computation examples based on reactor pressure vessels and water tanks for researching reactors.The sloshing amplitude is small at the frequency higher than1Hz;on the contrary,it is much bigger at the range of the lower frequency.In addition,the results showed that there exists a liquid splash during the rectangle container sloshing.
