| Abstract: | It is shown by some experimental results that the effect of fluid dynamic damping forces should be taken into consideration in the estimate of vortex-excited vibration of circular cylinder in uniform currents.This effect is added to the correlation model, and the fair agreement between the calculating and experimental results is obained.In order to avoid complicated caclulation in engineering problems, a set of response curves is given.Using these curves with some simple calculations, the amplitude of the resonant response of a circular cylinder vibrating can be.determined.The detailed steps and an example of this method are also given. |
