DEVELOPMENT OF A FORMULA FOR TOWING RESISTANCE FOR A WHEEL IN SOFT SOIL

THE DIMENSIONAL ANALYSIS AND THE EMPIRICAL CORRELATION ACHIEVED IN DEVELOPING A DIMENSIONALLY CORRECT FORMULA FOR APPROXIMATING THE TOWING RESISTANCE FOR EITHER A RIGID OR A PNEUMATIC-TIRED WHEEL ARE PRESENTED. A METHOD, CALLED THE MOVING CHORD CONCEPT, FOR HANDLING THE GEOMETRY OF THE COMPLEX PHENOMENON RELATING TO THE CONFIGURATION OF A PNEUMATIC TIRE IN SOFT SOIL (BASED ON EXPERIMENTAL EVIDENCE) IS PRESENTED. THE FORMULA THAT IS DEVELOPED SATISFIES QUITE EFFECTIVELY A WIDE RANGE OF TIRE SIZES. WHEEL LOADS, AND TIRE DEFLECTIONS IN TWO EXTREMES OF SOIL TYPE, NAMELY COHESIONLESS DRY YUMA DESERT SAND AND HIGHLY PLASTIC LOUISIANA BUCKSHOT CLAY. /NTIS/
