Vortex Induced Vibrations (VIV) experiments in water, conducted with flexible or elastically mounted rigid cylinders, under low values of mass-damping parameter, often reveal a large lock-in range, presenting a flat response region just after the amplitude curve peak. Previous phenomenological models, which treat the vortex wake dynamics with nonlinear oscillators of the Van der Pol type, are unable to predict this flat response region. The present paper re-addresses the phenomenological approach and shows that a consistent interpretation of a relevant hydrodynamic parameter, written as functions of reduced velocity, namely the added-mass, plays an essential role in improving analytical results.
