Abstract
This article presents the branch eigenmodes reduction method (BERM) applied to the identification of the heat flux dissipated during the friction between a disc rotating at variable speed and two brake pads. Temperature measurements used to identify fluxes in the disc and in the pad come from experimental data. One of the method's strength lies in its ability to greatly reduce the dimension of the numerical problem, while maintaining a satisfying precision on the whole computation domain. The reduction of the model enables us to perform the identification in a time compatible with real-time. The identified heat flux is coherent with the mechanical increase due to friction. Small discrepancies observed at the beginning of the friction sequence can be explained by wear.
