SELF-SYNCHRONIZATION OF VIBRATION EXCITERS OF VIBRATING MACHINES WITH BIHARMONIC OSCILLATIONS OF THE WORKING BODY

Abstract

The practical possibility of self-synchronization of two pairs of unbalanced vibration exciters with multiple rotation frequencies is considered. The problem is solved using the integral criterion of stability of synchronous movements. Formulas for synchronizing moments are obtained; conditions for the existence and stability of synchronous modes of motion of exciters. Equations are given for determining the phase shift angles in possible synchronous modes of motion of vibration exciters. Practical recommendations are formulated regarding increasing the stability of multiple-synchronous rotation of vibration exciters. Theoretical results are consistent with the results of computer modeling
