Vibration Analysis for Pipeline System of Petrochemical Pump House

LIU Hong-yu,WU Ming,SHI Cheng-jiang(College of Oil & Gas Engineering,Liaoning Shihua University,Liaoning Fushun 113001,China)  
According to the vibration situation of pipeline system in petrochemical pump house,simulation calculation forfirst ten orders natural frequencies of pipe was carried out by ANSYS software.The vibration acceleration signals of measuring points were tested by DASP v10 intelligent data acquisition and signal processing system.Through computer analysis,time domain wave spectrum and spectrogram of the corresponding pipe vibration were obtained.Compared with pipe inherent frequency calculated by the ANSYS software,the vibration causes were found out.
