The paper deals with the motion stability analysis and simulation of a discrete system that is composed of a mass interacting frictionally with a conveyor belt. There was assumed an experimentally identified dry friction model for steel-composite pair, depending on relative velocity, acceleration, time of adhesion and force rate. As a result of the system motion study, characteristic types of phase portraits were obtained and regions of qualitatively similar phase portraits were determined in the set of the system parametrs. It afforded possibilities for evaluation of the system behaviour for various values of friction model parameters and external damping, as well as of the system stability.
