Abstract :
The Radial fluid exciting force model and its dynamic characteristics is derived through the flow field simulation of AP-1000 nuclear main pump. The result indicates that complicated harmonics frequency vibrations is existed under the operating of nuclear main pump, and the coupling resonance of blades and vanes should be taken into serious consideration under the designing of nuclear main pump.
