Abstract:

A rotor can be on-line balanced by using a balancer with two balls and its forced vibration can be suppressed well. Although, the rotor, especially supported by rolling elements bearings, often shows nonlinear character practically because of weakly elastic restoring forces caused by the assembly error, etc., the relevant researches are mainly focused on its linear ones. For the rotor acted by weakly nonlinear elastic restoring forces and balanced by two balls, based on the research results about the control of principal vibration, the 1/2 order subharmonic vibration response characters and the effect of the mass of balls on the vibration amplitude were studied theoretically and numerically. It is concluded that the balls can balance the nonlinear rotor completely and suppress the amplitude of 1/2 order subharmonic vibration response well in the high speed region.<br/> &copy; 2017, Editorial Office of Journal of Vibration and Shock.
