摘　　要：反应堆结构的流致振动问题与核安全直接相关。为了完成反应堆堆内构件的流致振动分析,需要先对反应堆堆内构件振动特性进行分析。文中建立吊篮及其主要附属结构在空气和安装于反应堆压力容器内水下环境中的三维有限元模型,并分别进行了振动特性分析,使用ANSYS软件得到其梁式模态和壳式模态。The flow-induced vibration of reactor structures is directly related to nuclear safety.To complete the flow-induced vibration analysis of the components in the reactor,it is necessary to analyze the vibration characteristics of the components in the reactor.In this paper,the three-dimensional finite element model of the core barrel and its main ancillary structure in the air and the underwater environment installed in the reactor pressure vessel is established,and the vibration characteristics are analyzed respectively,and its beam mode and shell mode will be obtained by ANSYS.
