Highlights

• Densification of equal sphere packing under two-dimensional vibration was studied.

• Effects of vibration parameters, container size and feeding mode on packing density were analyzed.

• Max density can reach about 0.6757 for total feeding and 0.7131 for batch-wise feeding.

Abstract

Densification of mono-sized sphere packings using two-dimensional (2D) vibration was experimentally studied. The effects of vibration mode, amplitude and frequency, feeding method, and container size on packing density were systematically analyzed. Useful results were obtained.
