| Summary: | 碩士 === 國立中山大學 === 機械與機電工程學系研究所 === 93 === This study calculate the frictional temperature of the dissimilar metal pair by theoretical analysis. Analyze the frictional temperature rise at interface dividing into the flash temperature rise and the bulk temperature rise. According the frictional temperature rise, establish the model of the temperature rise at the first cycle and the quasi-steady state cycle. And then discuss the condition of asperity contact by the measurement of experimental temperature rise.
In the bulk temperature rise and the flash temperature rise, compare with the exact solution, the approximate solution of the average temperature rise that we derived have little error in specific range of Peclet number. Combine the approximate solution of the bulk temperature rise and the flash temperature rise to calculate the temperature rise of asperity contact at rubbing interface. We can evaluate the average contact length of asperity by measured values.
