摘要

This article describes a numerical model to reproduce vortex induced vibrations of a circular cylinder. It consists in a single degree of freedom non linear mechanical system, with characterizing parameters identified on the basis of experimental tests in order to reproduce the main features of VIV, in particular vibration amplitudes as function of wind velocity and the energy introduction by the blowing fluid into the mechanical system.
