摘　　要：介绍了CNP10 0 0吊篮组件模型在空气、静水中振动特性计算结果、试验结果和水力回路上的动水振动特性结果。结果表明 ,吊篮组件静水中的振动频率值较空气中下降很多 (一半左右 ) ,吊篮容器内、外的流体附加质量十分显著 ;随流速的增加 。The dynamical characteristics of a core barrel comp onent of CNP1000 nuclear reactor is studied by numerical calculation and test. The calculated and the test were on the vibration of the model in air and under still water, and the test also was on the vibration induced by flowing water. The calculation and test results show that the natural frequencies are as about half in still water as those in air, and that the speed of the water flow affects natural frequencies remarkably, they decreasing as the increasing in the speed of water flow.
