Random Vibration Spectrum Analysis of Large Pumping Station

According to the common vibration problem in the operation of large pumping station,finite element model of one large pumping station of south-to-north water transfer east route project was built in this paper and the free vibration characteristics were studied for resonance check.Based on the spectrum characteristics of pressure pulsations at measuring points of model test and the free vibration characteristics analysis,random vibration spectrum analysis method was used to calculate the vibration responses of the pump house.The calculating results had some reference meaning for anti-vibration safety evaluation of large pumping station.
