MEASUREMENT OF THE MAXIMUM ADHESION COEFFICIENT BY MEASURING STRESS IN A BEAD OF A TYRE

摘要

The invention relates to a method for determining the adhesion coefficient ν in the contact patch of a tyre on a road surface, whereby several points fixed in space are selected which are situated at different azimuths along the circumference in at least one bead of the tyre. Measurements of the variation in stress at said fixed points when the tyre rolls on the road surface and the measured signals are processed such as to give said adherence coefficient µ.
