Abstract
An analytical model has been developed for the determination of the friction heat distribution coefficient at the sliding interface of a stationary pin and a rotating layered disk. First, we analyzed the temperature distribution of a disk with a thin film subjected to a moving factional heat flow traversing with constant speed over the film surface. In addition to the lateral surface boundary conditions, convective cooling from the side faces is considered. A quasi-stationary theory is applied by use of a finite Fourier transformation. The solution of the heat conduction problem for the stationary pin is trivial. The heat distribution between the pin and the disk was obtained by matching the average contact temperatures. The effect of the thin film on the surface temperature distribution was studied.
