Flow induced vibration of tube bank structures, could has the harmful effects on a system. In the current work vibration of cantilever tube in the present of fluid flow is investigated. Forthis purpose the cantilever tube modeled as a simple mass-spring system. The numerical results are compared with Blevins and Coughran works (J. Fluids eng., vol.131, 2009), for reducedvelocity between 5 and 8, the mass ratio of 5.02 and the structural damping ratio of0.05. Numerical results predict the range of reduced velocity, which the amplitude of vibrations raises, but, the upper branch of amplitude is in lower values than in experimental. Finally variation of amplitude, L C and D C versus time, and vortex shedding are plotted.
