Abstract
Calibration test results are presented for a new automatic moving-hopper type sand pourer using a multiple-sieving pluviation arrangement, recently commissioned at the University of Cambridge. These results demonstrate its capabilities in preparing uniform sand beds using a typical fine, uniformly graded silica sand, for the purposes of centrifuge and 1-g modeling. Relative densities achieved were between 50 to 90%. The relative density of the sample was found to vary most with the sand flow rate, while varying the drop height has a relatively minor effect. The size and shape of the model container to be filled also has a sizable effect on relative density. Local variation of density along a particular dimension of a container was measured to be within ±4% of the mean value. Sample uniformity was confirmed by in-flight CPT tests.
