Some individual cases, associated due to presence of resonance dependence of pulsation characteristics on vibration system spatial parameter (H) and frequency of ω forced motions are considered. Real rheodynamic characteristics and their approximations for blown, moisture and different fraction vibration beds are given. Vibration layer classification is presented. Calculated and experimental data on dependence of gas resonance pressure pulsations (kPa) and vibration layer specific mass (kg/m2) on the system parameters are quoted. Good correlation of calculated dynamic characteristic and experimental data is obtained.
