In this paper, dynamic behaviors of a cantilever pipe conveying fluid are investigated by using experimental method. The experimental platform related to vibration experiment of the cantilever pipe conveying fluid is designed and established. The fundamental excitation is applied to study variations of the vibration amplitude of the pipe conveying fluid. The influences of flow speed, fundamental excitation and wall thickness on vibrations of the pipe are studied. The results demonstrate that the experimental parameters of the cantilever pipe conveying fluid have a significant effect on the critical flow velocity associated with flutter instability. Under the fundamental excitation, the vibration amplitude of the pipe increases significantly. When the frequency of the fundamental excitation is close to the natural frequency of the cantilever pipe conveying fluid, the vibration amplitude of the pipe reaches the maximum value.
