Abstract

Dynamics of the vibration machine taking into account the elasticity of coupling of the unbalance vibration exciter with a limited- power electric motor is considered. A solution describing the relative torsional oscillations of the vibration exciter and motor rotors in steady (near-steady) motion modes and the formula for vibrational torque was obtained. The above mentioned dependencies are also valid for the case of motor speed “sticking” in the natural frequency region of the vibration machine. The correlation between the vibrations of the unbalance drive and the vibration machine bearing body is established. Recommendations for avoiding resonant vibrations of the vibration machine drive are formulated.KeywordsVibration machineUnbalanced driveElastic couplingSomerfeld effect
