A Multi-scale Contact Temperature Model for Dry Sliding Rough Surfaces

Abstract A multi-scale flash temperature model has been developed and validated against existing work. The core strength of the proposed is that it can be adapted to predict contact temperatures occurring in various types sliding systems. In this paper, used investigate how different surface roughness parameters affect temperatures. results show for decreasing Hurst exponents as well increasing values high-frequency cut-off, maximum increases. It was also shown effect does not influence average interface temperature. predictions were data from an experiment conducted a pin-on-disc machine. This showed importance including wear when simulating development system.
