Abstract
A 2D coupled temperature-displacement FE model is developed for a pad-disc brake system
based on a restricted rotational pad boundary condition. The evolution of pressure, heat
flux, and temperature along the contact interface during braking applications is analysed
with the FE model. Results indicate that different rotational pad boundary conditions
significantly impact the interface pressure distribution, which in turn affects interface
temperature and heat flux distributions, and suggest that a particular pad rotation condition
is most appropriate for accurately modelling friction braking processes. The importance of
the thermal contact conductance in the analysis of heat transfer in friction braking is established, and it is confirmed that the heat partition ratio is not uniformly distributed
along the interface under normal and high interface thermal conductance conditions.
