The main purpose of this study is to analyze the thermomechanical behavior of the dry contact between the brake disc and pads during the braking phase. The simulation strategy is based on softawe ANSYS11. The modeling of transient temperature in the disc brake is actually used to identify the factor of geometric design of the disc to install the ventilation system in vehicles. The thermal-structural analysis is then used with coupling to determine the deformation established and the Von Mises stress in the disc, the contact pressure distribution in pads. The results are satisfactory compared to those of the specialized literature.

Głównym celem pracy jest analiza zjawisk termomechanicznych w obszarze suchego styku pomiędzy tarczą hamulca a klockiem ciernym występujących w fazie hamowania. Strategia symulacji jest oparta na oprogramowaniu ANSYS11. Wyniki modelowania stanów przejściowych temperatury w tarczy hamulca wykorzystano do identyfikacji geometrycznych współczynników projektowych, użytych do instalacji systemu wentylacji. Sprzężona analiza strukturalno-termiczna jest następnie użyta do wyznaczenia deformacji tarczy, naprężenia Von Misses’a, oraz rozkładu ciśnienia kontaktowego w klockach ciernych. Wyniki analizy wykazują zadowalającą zgodność z podobnymi podawanymi w literaturze.
