| Abstract: | Dynamic characteristic tests and shaking table tests of nuclear power station equipment (an IS type centrifugal water pump) are carried out. By using the free vibration attenuation method, the white noise exciting method and the half power point method, natural frequencies and damping ra- tios of the water pump in three directions are measured respectively. The method of modeling floor acceleration processes is presented. On the basis of the modeling method presented in the paper and floor response spectra, floor acceleration processes are modeled, and shaking table tests of the water pump are carried out under the condition that the water pump works. |
