INFLUENCE OF CONNECTION ELASTICITY OF THE UNBALANCED VIBRATION EXCITER WITH AN ELECTRIC MOTOR ON OSCILLATION OF VIBRATION MACHINE`S DRIVE

Abstract

The results of the study of the dynamics of vibration machines with unbalance drive taking into account the elasticity
of its links are given. An expression describing the torsional vibrations of the drive near the stationary modes of rotation of
the vibration exciter and the formula that allows estimating the dynamic load of the engine is obtained. The dependences take
into account also the case of the "sticking" of the angular velocity of the motor in the zone of the natural frequencies of the
vibrator. It is shown that when starting the machines in the case of the Somerfeld effect, resonant oscillations of the elasticdamping elements are excited, which connect the rotors of the engine and the pathogen. It is established that in the presence
of an elastic element in the drive, the frequencies of the vibratory machine's natural oscillations are added to its critical
frequencies.
