Comportement thermique d'un disque tournant soumis à des sources de chaleur surfaciques discrètes
[Thermal behaviour of a rotating disc subjected to discrete surface heat sources]
Comptes Rendus. Mécanique, Volume 337 (2009) no. 8, pp. 616-620.

Analytical model is developed in this Note to determine the 3D temperature distribution in a rotating disc subjected to multiple surface heat sources. The Fourier and Hankel integral transforms are used to perform the analytical calculations. The expression obtained by this way is explicit and allows one to compute the temperature without restriction on the rotating speed and the physical properties values. Some practice industrial applications are concerned by this calculation such the contact between pad and disc in braking systems, or the pin-on-disc tribological devices.

Un modèle analytique est développé dans cette Note pour déterminer la distribution tridimensionnelle de la température dans un disque tournant soumis à des sources de chaleur surfaciques multiples. Les transformées intégrales de Fourier fréquentielle et de Hankel finie sont utilisées pour conduire les calculs analytiques. L'expression obtenue par cette technique est explicite et permet de calculer la température sans restriction sur les valeurs de la vitesse de rotation et des propriétés physiques. Parmi les applications industrielles pratiques concernées par ce modèle on peut citer le contact plaquette-disque dans les systèmes de freinage, ou bien les dispositifs tribologiques pion-disque.
