Study of self-synchronization of unbalanced vibration exciters of a biharmonic vibration drive

The possibility of dynamic synchronization of two pairs of unbalanced vibrators with multiple rotation frequencies is considered. The research was carried out using the integral criterion of stability of synchronous motions and the method of direct separation of motions by Prof. I. Blekhman. The possibility of obtaining biharmonic rectilinear vibrations of the working body of a vibration machine with two pairs of kinematically uncoupled unbalanced vibrators with multiple frequencies is shown. The possibility of obtaining steady-state two-frequency vibrations using a biharmonic vibratory drive without kinematic transmissions is confirmed by computer modeling.
