MEASUREMENTS OF FORCE BETWEEN TYRE AND ROAD, IN PARTICULAR OF SIDEWAYS FORCES ON COMMERCIAL VEHICLES

KRAFTMESSUNGEN ZWISCHEN REIFEN UND FAHRBAHN, INSBESONDERE VON SEITENKRAEFTEN AN NUTZFAHRZEUGEN

THE OBJECT OF THE PROJECT IS TO MEASURE THE SIDEWAYS FORCES AND THE CHANGING RESULTS OF ALL THE FORCES WHICH OCCUR BETWEEN THE TYRES OF COMMERCIAL VEHICLES AND THE ROAD. FOR THIS PURPOSE A FIVE-COMPONENT MEASURING DEVICE WAS DEVELOPED WITH WHICH PEAK LOADS OF UP TO 3.5 METRIC TONS OF VERTICAL FORCE, 0.9 METRIC TONS OF CIRCUMFERENTIAL FORCE AND 0.8 METRIC TONS OF TRANVERSE FORCE CAN BE MEASURED. THE MEASURING SYSTEM IS TO BE FURTHER DEVELOPED SO THAT IT CAN COPE WITH VERTICAL FORCES UP TO 12 METRIC TONS, HORIZONTAL LONGTUDINAL FORCES UP TO 4 METRIC TONS AND LATERAL FORCES UP TO 5 METRIC TONS. THE MEASURING DEVICE IS BEING MANUFACTURED AND TESTED FOR THE AXLE OF A TRAILER. AT A LATER DATE MEASUREMENTS OF VARIOUS AXLE AND TYRE ARRANGEMENTS ARE ANTICIPAED.
