Abstract: The internal energy dissipation of the granular block under the vertical vibrating was studied through the experiment. The average flight time of four granular blocks for different vibrating strength was measured. Dynamic analysis of the experimental results was carried out. The quantitative relationship of the average flight time and the vibrating strength and the internal friction factor was used to fit the relationship for fitting the experimental data, the fitting results are well agreed with the experimental results. Theoretical analysis of the experimental results show that the internal energy dissipation of different internal structure depends on the particle size, particle viscidity and vibrating frequency for a given vibrating strength. The internal energy dissipation character is mainly the collision dissipation of each other.

Key words: granular matter, collision, average flight time, internal energy dissipation
