Keywords： unsteady flow

An excited experiment system of 20# steel pipe was established with oil cylinder,20# steel pipe,frequency converter,pump station and wave exciter generating unsteady flow artificially.The experimental results showed that the 20# steel pipe could vibrate with the excitation of unsteady flows,and the vibration was periodic,instead of a harmonic one.Particles on the front and rear positions of pipe vibrated synchronously,and the vibration intensity of the pipe's two ends was greater than in the middle.System pressure and wave exciter' s frequency had much influence upon pipe's amplitude.Pipe's vibration frequency was little affected by system pressure,and its value was close to the wave exciter's.Therefore,the active control of pipe's vibration can be realized by setting system pressure and adjusting frequency converter's frequency.
