DETERMINATION OF THE ADHESION OF CAR TYRES TO VARIOUSLY WEATHERED SURFACES OF THE BAST INTERNAL DRUM TEST RIG

DIE GESTALTUNG DER VERKEHRSTECHNIK ZUR ERFASSUNG DES KRAFTSCHLUSSES VON PKW-REIFEN AUF VERSCHIEDEN BEWITTERTEN FAHRBAHNEN DES INNENTROMMELPRUEFSTANDES DER BAST (IPS)

A STUDY IS TO BE MADE OF HOW THE TECHNICAL POSSIBILITIES OF THE DRUM TEST RIG CAN BE APPLIED TO THE EVALUATION OF CRITICAL ADHESION BETWEEN CAR TYRES AND DRY, WET AND ICY ROADS. THE STUDIES ON THE RIG ARE TO BE CHECKED BY REFERENCE TO THE LITERATURE TO SEE WHETHER THEY ARE VALID FOR PRACTICAL ROAD CONDITIONS. POSSIBLE VARIATIONS IN THE MOST IMPORTANT PARAMETERS FOR THE ADHESION BETWEEN CAR TYRE AND ROAD ARE TO BE TESTED ON THE RIG. THESE INCLUDE DRIVING CONDITIONS (WHEEL LOAD, SPEED, TYRE ANGLE, TYRE TYPE) AND ROAD CONDITIONS (DRY, WET, ICY).
