performance of a tire in a traction state can be evaluated by acceleration of the rotation of the tire by application of driving force to the tire. In the waveform of the graph, Fx moves in the positive direction with time. The maximum value of Fx can be said to be an index of ...
Overall, different systems are expected to provide different friction indexes because of the variable measuring principles. There have been attempts to develop a harmonized friction value (aiming to be non-device specific), such as the International Friction Index (IFI) developed by the PIARC World ...
