THE INFLUENCE OF THE ROAD SURFACE ON THE NOISE GENERATED BY TYRES WITH NO TREAD AND A CONTRIBUTION TO CLARIFY THE PROBLEM

DER EINFLUSS DER FAHRBAHN AUF DAS GERAEUSCH PROFILLOSER REIFEN UND EIN BEITRAG ZU SEINER ERKLAERUNG

THE INFLUENCE OF A DRY ROAD SURFACE ON THE NOISE CREATED BY A FREELY ROLLING TYRE IS INVESTIGATED. SURFACE GRIP AS A MEASURE OF FORCE TRANSMISSION BETWEEN THE TYRE AND ROAD SURFACE WHEN WET IS ESPECIALLY CONSIDERED. SURFACE GRIP IS DETERMINED BY THE STUTTGART "FRICTION METER", WHILST NOISE IS MEASURED USING A SPECIALLY DEVELOPED MEASURING TRAILER, WHICH PERMITS THE MEASUREMENT OF NOISE LEVEL WITHIN FLOWING TRAFFIC. THE RESEARCH WORK CONCENTRATES ON THE QUESTION WHETHER A NOISE-FREE 'TYRE TO ROAD SURFACE' COMBINATION SHOULD BE TAKEN IN ACCOUNT AS DETRIMENTAL WHEN ROAD SAFETY ASPECTS ARE CONSIDERED. IT IS SHOWN THAT NOISE FREE ROAD SURFACES CAN SIMULTANEOUSLY HAVE HIGH GRIPPING PROPERTIES. USING HIGH-FREQUENCY ANALYSES AND THEORETICAL CONSIDERATIONS, A HYPOTHESIS ON THE GENERATION OF TYRE NOISE IS GIVEN. THIS SHOWS THAT TYRE NOISE IS GENERATED BY RADIAL VIBRATIONS AND TANGENTIAL FRICTIONAL VIBRATIONS. WHICH TYPE OF VIBRATION DOMINATES DEPENDS ON THE TEXTURE OF THE ROAD SURFACE.
