Abstract
This study explores the dynamics of a spherical intruder impacting a vertically vibrated granular bed using discrete element method (DEM) simulations. The system consists of 25,000 particles contained in a box with sinusoidal bottom wall vibrations ranging from 25 to 500 Hz. The intruder is dropped from a fixed height with varying initial velocities. Results show that the vibration frequency and initial velocity significantly influence the intruder’s penetration depth and hence the final resting position. Lower vibration frequencies allow deeper penetration due to reduced granular agitation, while higher impact velocities enhance penetration through increased momentum.
