The autoresonant electric drive of the swinging movement pendular vibration exciter vibration jaw crushers

Article preview

To use of the autoresonant electric drive of swinging movement for creation of an oscillative motion of crushing jaws of vibrating jaw crushers it is offered in this article. The control system of the electric drive is developed. The results of imitating and physical modelling of the autoresonant electric drive are presented.

Mathematical and simulation models of the inertial resonant jaw crusher with the electric drive of the reciprocating-rotating motion

Article preview

Mathematical and imitating models of an inertial resonant crusher with the electric drive of returnable, rotary movement are developed. Operating modes of electromechanical system on resonant (own) frequency of system are investigated (researched) at various representations of loading (viscous, equivalent viscous, dry friction and their combinations) at symmetric and asymmetrical cycles of loading, both in opened, and in the closed control system.
