METHODS FOR MEASURING LOAD TRANSFER THROUGH VEHICLE TIRES TO THE ROAD SURFACE

IN ORDER TO DETERMINE IF VARIATIONS IN READINGS OBTAINED FROM ELECTRONIC WEIGHING SCALES COULD BE ATTRIBUTED TO THE UNDULATING LOAD CHARACTERISTICS OF A MOVING VEHICLE, THREE DIFFERENT MEANS OF MEASURING WHEEL LOAD WERE MEASURED SIMULTANEOUSLY. THE AXLE-HOUSING STRAIN METHOD AND THE BULGE METHOD WERE FOUND TO BE LESS PRACTICAL THAN THE CHANGING TIRE PRESSURE METHOD. THE METHOD ALSO ENABLES THE DIFFERENT SUSPENSION SYTEMS NOW IN USE TO BE COMPARED. IT IS CONCLUDED THAT DIFFERENCES OF MORE THAN FIVE PERCENT BETWEEN STATIC WEIGHT AND SCALE READINGS ARE DUE TO THE OSCILLATION CHARACTERISTICS OF A VEHICLE IN MOTION.
