✦ Synopsis

The companion paper, Part I, is a theoretical modelling which consists in developing a vibro-acoustic calculation of a rotating rotor on bearings with a numerical simulation of mechanical defects. Controlled error and small computation time distinguish the method. This paper presents the experimental study which was obtained for a test bench composed of three supports (motor, rotor on bearings and speed reducer), in order to simulate such mechanical defects. Comparisons between theoretical and experimental results are presented.
