| Abstract | In the dynamic study of rotors is often overlooked due to friction when the power equation of the rotating system, which affects the simulation, results to critical gearshifts. In this study, we reviewed the implementation of the rotors equations taking into account the dry friction (Coulomb friction) on the bearings say "ball bearing", that for the numerical simulation using the finite element method; dynamic approach to even the reaction of our model vis-a-vis rotor harmonic loads such as unbalance and reaction to friction. These same results will be introduced in our active balancing future system of rotating machines that will use the method of influence coefficients and intelligent masses who will balanced the system in a state of imbalance. 22 Congres Francais de Mecanique Lyon, 24 au 28 Aout 2015 Mots cles : Vibrations, frottements sec, frottement de coulomb, balourd, equilibrage actif, coefficients d'influence. |
