Abstract
The article presents the results of resonant oscillations theoretical research of the telescopic screw - granular material system caused by external periodic forces. In the theoretical part a mathematical model of bending vibrations of an elastic body is described, which rotates along a fixed axis with a constant angular velocity, provided that it moves with a constant relative linear velocity along the elastic body. In the experimental part, according to the obtained equations, it has been established for the various kinematic characteristics of the system, a telescopic screw-granular media of amplitude passing through resonance at the frequency of external periodic perturbation. The results of experimental research and recommendations for the selection of constructive kinematic for telescopic screw conveyor have been presented.
