Abstract
Results obtained from experimental studies of the motion of solid bodies through a granular medium under a time-varying load are presented. Dependences of the average velocity of a body on the driving frequency are obtained, and the resonance behavior of these dependences is observed. It is established that the experimental value of the resonance frequency has a universal meaning and is fundamentally and closely related to the structure of the granular material. The structural features of a granular medium are qualitatively described, along with the correlation between them and the result of the study.
