Simulation modeling of the resonant electric drive of the reciprocating-rotating motion of the dynamically balanced drilling projectile on the load-carrying cable

Article preview

Imitating modelling electromechanical oscillatory system of bacr-rotary movement with dry and equivalent viscous frictions is considered, the quantitative estimation of replacement of dry friction equivalent viscous is given at work of system on own frequency.
