| Sumario: | An experimental study was conducted to evaluate the
effect of the applied load and moving speed on the free rotating rubber
specimen contact area on a smooth-surfaced glass plate. The contact area of the
rubber specimen and flat surface was observed using fluorescence microscopy by
utilizing ultraviolet as an excitation light source and pyranine as a dye
substance. The apparent contact area between the rubber specimen and the flat
surface was measured using image processing software based on the Otsu
thresholding method. The result reveals an increasing
trend line due to applied normal load dependency, which agreed with the Hertz
theory. On moving-speed influence, the trend line of rubber contact increased
at a lower speed, reaching the highest value at a moving speed of 8 mm/s, and decreased
as the moving speed increased further. |
