000014082 520__ $$2eng$$aA vibrationally-fluidized granular flow (VFGF) presents a fluid-like bulk flow behaviour superimposed on local velocity fluctuations due to particle collisions and the Vibrating container walls. The impacts between particles and workpieces are utilized in manufacturing processes such as Vibratory surface finishing, although process control and optimization remain mostly experience-based due to the complexity of VFGF. Recent studies have shown encouraging agreement between experiments and discrete element predictions of bulk and local velocities in VFGFs, enabling extensive observations on how container wall motion and the resulting contact forces influence the bulk and local properties of the granular bed. The present work used discrete element modelling to examine the wall-media contact forces and their connection to both the formation of bulk convection and the local impact velocity distribution throughout a VFGF. The results have explained the development of steady- state VFGF, and have been used to calibrate a model for normal wall forces.
