Determining frictional connection between tyres and road surface - by evaluating measured variations in local stresses, expansions or deformations to determine maximum possible coefficient of friction

摘要: Determining the frictional connection between vehicle tyres and road surface involves detecting variation of local stresses, expansions or deformations at one more points on tyre in least horizontal direction normal direction. The measured values are evaluated to determine maximum possible coefficient friction. measurements can be made point simultaneously several points. USE/ADVANTAGE - For automatic, continuous measurement characteristics surface, enabling determination limits stable operation before reaching them.
