Abstract
An examination of the heat partition ratio between the friction surfaces of a disc
braking system is presented using finite element analysis (FEA). This includes a 2D
static analysis of two semi-infinite bodies in contact with and without an interface
layer which represents the interface tribo-layer (ITL). An analytical approach with a
finite difference solution was used for cross-comparison with the static FE models.
Results from the static model have provided the boundary conditions for a 2D
dynamic model, where one rectangular block slides on another (fixed) rectangular
block. The effects of normal loads and real contact area have also been studied.
