Full TextAbstract
Vortex-induced vibrations (VIV) are a well-known phenomenon to engineers. The practical sig-nificance of VIV has led to a large number of fundamental studies. In this paper, the behavior of an elastically mounted cylinder, subjected to (VIV), is investigated by a wake oscillator model. First the spectral analysis of the model is used as a criterion for the predicting of the lock-in range, in both low and high mass-damping ratios. Then the validity of using a combined mass-damping parameter for predicting of the maximum structure displacement amplitude at lock-in, is analytically investigated.
