A STUDY OF PRESSURES GENERATED BY VIBRATING ROLLERS

THE PAPER IS CONCERNED WITH THE MEASUREMENT OF PRESSURES IN SAND UNDER TOWED VIBRATING AND NON-VIBRATING STEEL WHEEL ROLLERS TO DETERMINE THE EFFECTS OF THE ROLLERS PARAMETERS. SMALL EMBEDDED PRESSURE CELLS, COUPLED TO AN AMPLIFIER AND RECORDER, WERE USED TO GIVE A CONTINUOUS TRACE OF PRESSURE WITH TIME. THE EFFECT OF WEIGHT, WIDTH AND DIAMETER OF THE DRUM FOR THE NON-VIBRATING ROLLERS ON PRESSURE FOLLOWED THE EXPECTED PATTERN. WITH VIBRATING ROLLERS, THE RESULTS WERE VARIABLE; HOWEVER CENTRIFUGAL FORCE DID APPEAR TO CORRELATE WITH PRESSURE, BUT WITH A SUBSTANTIAL LOSS. THE RATIO OF THE PEAK VIBRATING PRESSURE TO NON-VIBRATING PRESSURE WAS GENERALLY ABOUT 2. THE RESULTS WERE COMPARED WITH DENSITIES ACHIEVED ON THREE MATERIALS. AS EXPECTED, THE MAGNITUDE OF THE VIBRATING PRESSURE HAD NO INFLUENCE ON THE DENSITIES OBTAINED IN 6 IN. LAYER OF TWO COHESIONLESS MATERIALS. HOWEVER, THE VALUE APPEARED TO CORRELATE WITH THE DENSITIES IN CLAY. /AUTHOR/
