DYNAMIC FORCES EXERTED BY MOVING VEHICLES ON A ROAD SURFACE

AN APPARATUS IS DESCRIBED FOR MEASURING THE FORCES EXERTED AT A POINT ON A ROAD SURFACE BY THE WHEELS OF MOVING VEHICLES. DETAILED RESULTS ARE PRESENTED OF MEASUREMENTS OF THREE FORCE COMPONENTS:VERTICAL FORCE, AND LONGITUDINAL AND TRANSVERSE HORIZONTAL FORCE COMPONENTS. THE INVESTIGATION INCLUDED A STUDY OF THE INFLUENCE ON THESE FORCES OF TIRE INFLATION PRESSURE, SPEED, ACCELERATION, WHEEL LOAD, HEIGHT OF MEASURING STUD ABOVE ROAD SURFACE, ETC. SEVEN DIFFERENT VEHICLES WERE USED COVERING A RANGE OF WHEEL (TIRE) LOAD FROM 135 KG TO 2,540 KG (300 LB TO 5,600 LB), AND A SPEED RANGE OF 15 KPH TO 75 KPH (6 MPH TO 47 MPH). /AUTHOR/
