The periodic motion, consisting of continual hops, of a particle under the action of a vibrating machine (e. g. vibratory conveyor, screen, metering machine). After studying the region of periodic motion in the vertical plane xy normal to the track plane xz, we analysed the stability to small perturbations of the periodic motions obtained.
