The article provides a comparative analysis of energy consumption for the resonance and superresonance vibration conditions of the working body in vibration-type process machines with an unbalanced vibration exciter. An algorithm for estimating vibration exciter parameters required to ensure the given amplitude and frequency of oscillations of the working body is described for both modes. The proportional law of frequency regulation by an asynchronous motor is taken into account. The driving torque developed by the motor is described by its static characteristic using the Kloss formula. When assessing the power consumption, the losses occurring in the elastic suspension of the vibration machine are described by the linear viscous damping model and the losses associated with the rotation of the rotor relative to the housing are taken into account as the moment of dry friction in the bearings of the electric motor. The occurrence of reactive power and the efficiency of the electric motors used in the resonant and superresonant vibration machines are also taken into account. The electric motors are selected with due regard to the required starting torque and the balance between the moments of all resistance forces and the driving torque in the operating mode. The processes of start-up and ramping-up to the operating mode of oscillations are studied for vibration machines, when using the electric drive selected. The results obtained are compared with the calculated parameters of existing vibration machines.
The study was carried out under the grant issued by the Russian Science Foundation (project No. 18-19-00708).
