Temperature and Coning Analysis of Ventilated Brake Disc Based on Finite Element Technique 2007-01-3670

The ventilated disc brake is divided into a disc with several vents, and the pads with the three dimensional geometry. The frictional heat can cause high temperature during the braking process. The thermal distortion of the brake disc can affect the performance of brake system. The object of present work is determination of temperature distribution and thermal distortion in the disc by two dimensional thermal analysis. During brake, heat flux and convective transfer coefficient are considered as a function of time. The brake disc temperature is found to be satisfactory compared with that of the conventional three dimensional analysis. Thermoelastic deformation of the disc is found from the same axisymmetric finite element model with equivalent mechanical properties. The analysis results are also compared to the measured data in the brake disc thermal experiment.
