核级阀门抗震分析与研究

Study on anti-earthquake analysis of nuclear valve

介绍了核级阀门抗地震分析的要求。对有、无预应力模态分析的两种情况进行了对比研究。同时,对使用ANSYS软件进行模态分析的计算过程进行了简要叙述。

This article briefly describes the requirements of anti-earthquake of nuclear valves.Study on the modal analyses has been carried out based on with and without prestresses.At the same time the calculation of modal analysis porformed with ANSYS software is also described.
