Abstract: Fade test results of a ventilated disk brake rotor with pegs-wing performed by means of an inertia dynamometer, consisting of 14 repeated brake applications from an initial brake speed of 160 km/h down to 0 km/h, with constant deceleration are shown. The first brake application test results are compared to the FEM numerical predictions with MSC Visual Nastran on the entire disk. These conform well to the experimental data, although numerical thermal field is slightly higher than the experimental one. Besides, ventilated disk brake rotor shows great dimensional stability and the ability to dissipate a great amount of thermal flow.

Keywords: disk brake rotor; finite element analysis; FEA; thermal stress; fading test procedure; friction coefficient; brake temperature; braking analysis; thermal flow; dimensional stability; vehicle modelling; vehicle testing; disk brakes.
