System for determining the resonance phenomenon of a rotating body.

摘要

1. System for determining the resonance phenomena of rotating bodies disturbing the movement of a rotating structure by virtue of the dissipation of the internal energy of the bodies which it comprises, this system comprising remote control means for the driving under vacuum of the said structure about its axis IZ and also telemetering means defining the speeds and variations of attitude of the rotating structure, characterised in that the structure (1) is coupled to a motor (14) driving an inertia flywheel (17) in such a manner that the system is placed under the dependence of the rotation of the axis IZ of the said rotating structure and the own rotation of the motor (14) mounted on the structure (1), the shaft of the motor driving an inertia flywheel (17) with an axis substantially parallel to that of the rotating structure (1) so as to cause variation of the equivalent ratio of the inertia moments.
