An ultraviolet-induced fluorescence method was used to measure the contact area between a cylindrical rubber wheel and flat glass. The experiment was carried out using pyranine as the fluorescence dye, and three variants of load in static and dynamic conditions. The contact area was captured by high-speed camera and analyzed using s software. Results showed that the contact area became wider as the applied load increased from 39.2 to 117.6 N in the static condition; in the dynamic condition, however, the contact area decreased as speed increased from 22.5 to 90 mm/s.
