摘要

In order to increase homogeneity with a higher packing density of vibrocompaction fuel, we investigated the effect of size ratio and shape of multi-size powders on vibratory compacting, and the size segregation phenomenon which commonly occurs with vibratory compacting. Spherical glass beads and irregular glass particles were used in the present vibratory compacting. We propose a segregation model that expresses the relation between size segregation, size ratio and amplitude. Under the shaking condition of this study, our model well agreed with the experimental results. Before and after shaking, compacting behavior of the samples were observed by X-ray computed tomography (X-ray CT).
