Research Abstract |
The real area of contact between a tire (rubber) and a glass plate under wet condition with thin water film was visualized using light induced fluorescence method. It was aimed to establish experimental technique analyzing the relation between friction generation and the real area of contact in fundamental manner. The real contact area extraction technique by the Gaussian distribution fitting to the intensity histogram obtained from the visualized image was developed. And its validity was confirmed by the comparison between the theoretical result of Hertzian contact and the experimental result. A tester to measure reciprocating sliding friction and rolling-sliding friction was developed. It was confirmed that the frictional force measurement accuracy was suitable for measuring friction on ice and also that the frictional force and the real contact area could be measured at the same time.
