Temperature Measurement of the Contact Surface from the Analysis of Temperature Distribution of the Hot Spots
초록
A method has been developed to measure the surface temperature in a sliding tribosystem. The determination of the surface temperature was inferred from the temperature of hot spots which were generated by frictional heat. The temperature of hot spots was determined by regressing those digitized data on Gecim-Winer's theoretical model. The experimental results are discussed considering the important factors such as PV and frictional heat. The surface temperature rise is related to the thermal conductivity in low PV range. As PV increases, it reaches nearly constant value called the critical temperature.
