Abstrakt: Dynamic analysis is carried out for a system in which the alternating motion of an oscillator is transformed into rotary motion of an unbalanced weight under the action of an electrodynamic vibration exciter. The conditions of the existence and stability of stationary modes of forced oscillations are investigated by the averaging method in the first approximation. The presence of regions of instability of below-resonance modes and a significant narrowing of the region of stable modes are revealed with the consideration of drive characteristics. The mechanical characteristics of a system using it as a synchronous vibratory motor are determined. An example is represented in which the average static moment at the output of the slider-crank mechanism does not exceed the moment in the considered method for motion transformation with maximum vibrational amplitude.
