DYNAMIC SYNCHRONIZATION OF INERTIAL VIBRATION EXCITERSBIHARMONY VIBRATION DRIVE

Abstract

The possibility of obtaining stable biharmonic oscillations of a vibration machine with kinematically uncoupled inertial vibration exciters is considered. The dynamic synchronization of two pairs of inertial vibration exciters with multiple rotation frequencies is investigated. The problem is solved using the integral stability criterion (extreme property) of synchronous movements. Phase shifts in possible synchronous movements of vibration exciters, conditions for the existence and stability of synchronous movements are established. Formulas for vibration moments that ensure self-synchronization of vibration exciters are obtained. Theoretical results are confirmed by numerical modeling.
