The objective of this article is to identify a model able to represent the first harmonic behavior of a rigid cylinder undergoing VIV in the most different cases of a rigid cylinder supported by a spring/damper system. This analysis of the first harmonic behavior is made considering three different non-dimensional variables: the damping coefficient, the reduced velocity and the mass ratio. The challenge is to define a model that represents the changes on the lock-in zone considering the different combination of damping coefficient and mass ratio thus able to represent the different real systems. Two new phenomenological models using the Van der Pol oscillator are studied. They follow the framework of the phenomenological model proposed by Facchinetti et al.
