Tire camber angle influence on tire-pavement noise

摘要

The influence of tire camber angle on tire-pavement noise was discussed in this paper.Laboratory experiment was performed at the Gdansk University of Technology. The noisemeasurements were performed for two tires rolled on two surfaces: smooth and rough. Thecamber angle of the each tire was changing with the step of 1.5° from -6° to +3°. The soundpressure levels in dB(A) for speeds of 30, 50, 70, 90, 110 and 130 km/h were acquired. Theanalysis of the influence of tire camber angle on tire-pavement noise was presented. It wasconcluded that it depends on: road surface, tire speed and tire camber angle value and sign(positive or negative). No correlation had been found.
