Features of the Control Actions Formation During the Start-up of Vibration Machines at Passing of the Resonance Zone

Abstract

The features of the resonance zone passing during the start-up of an above resonance vibration machine were considered. It has been noted that intense vibrations of the vibration machine actuating device occur during passing of the resonance zone, which leads to a number of negative consequences. The analysis of existing methods for reducing the amplitude of resonance oscillations using electric drive systems were carried out. It was suggested the application of a frequency-controlled electric drive to the above resonance vibration machines for the passing of the resonance zone, which will allow the use of drive motors with the power necessary for operation in the technological mode. Using mathematical modeling, the research of the frequency start-up of the above resonance vibration machine during the formation of a voltage-frequency characteristic of various forms have been carried out.
