Brake system which is the safety system has a high demand for heat fade. To predict the temperature of brake, especially in continuous braking conditions, is important for heat fade. In this paper a transient numerical heat transfer model is developed to estimate the time-dependent temperatures distribution in ten-cycle braking condition. When the highest temperature is determined, braking friction heat is directly applied to the friction surface in the form of heat flux; the braking heat dissipates to the ambient air via convection heat transfer and thermal radiation, which are boundary conditions. Temperature predicted by two-dimensional thermal analysis is acceptable compared with conventional three-dimensional thermal analysis and experimental dynamometer drum temperature measurements.
