Energy transfer and dissipation in a vibrated granular bed was studied by DEM simulations, and the energy profile in the granular bed of the same size and binary mixture were obtained. The results show that the energy transfer and dissipation in the granular bed are influenced by the vibration parameters (vibration amplitude and frequency). Along the bed height, the kinetic energy of grains decreases at high vibration frequency, while it increases at low vibration frequency. For the granular bed constituted by a binary mixture, the total kinetic energy is influenced by the grain distribution of mixture in bed beside frequency and amplitude. For low frequency amplitude vibrations, the granular bed with “Reverse Brazil Nut” distribution has lower energy. While, for high frequency vibration, the energy of bed with “Brazil Nut” distribution is much lower.
