Abstract

When the disks of the rod fastening rotor were contacted with each other, the contact thermal resistance between the contact surfaces would play a critical role in heat transfer and the distribution of temperature field. On the basis of the surface fractal characteristics, combining Mandelbrot - Tian (M - T) fractal network model and the classical conduction theory, the Cantor set, which was not dependent on the observation scale, was chosen to obtain the relationship between the pressure and the heat transfer coefficient of contact surfaces. The rotor transient temperature field distribution was obtained through determining the contact thermal resistance. It was found that the thermal conductivity caused by the pre-tightening force had a little influence on the transient temperature field. Therefore, when the rotor dynamic characteristics were analyzed, the influence of the transient temperature field could be ignored.
