ABSTRACT={This article is dedicated to the study of the vibratory behavior of a rotor. The study presents a set of
scientific techniques on modeling and simulation of the vibrations of a rotor of a turbomachinery driven in torsion. This study helps to understand from the dynamic study the origin of the noise and vibration of a rotor; the study allows from the Rotorinsa software to highlight the effects of unbalance on a rotor. To develop the equations of the vibratory motion of the rotor, we used Lagrange’s energy approach. To succeed, a two wheeled model carried by a tree supported by two
hydrodynamic bearings is chosen according to the characteristics of the studied rotor. Each element of the rotor is defined by its finite element. The analytical resolution of the differential equations that characterize the vibratory behavior of the rotor is difficult manually. The numerical approach using the finite element method, programmed on Rotorinsa software allowed to perform dynamic rotor analysis.}}
