… theoretical and practical methods are given for the flexible rotor balancing far from critical rotation frequencies, as the methods do not require to know forms of oscillation, dissipation and elasticity-and-inertia characteristics, with use and unuse testing masses.

CONT

[Caractéristiques dynamiques d’un rotor indéformable.] Lorsque la vitesse de rotation augmente, la fréquence devient égale à un moment donné, soit à la fréquence du mode cylindrique, soit à celle du mode conique. Ces fréquences sont appelées fréquences de rotation critiques, l’amplitude du tourbillonnement du rotor peut prendre alors des proportions dangereuses.
