Analytical formulae were obtained to quickly determine the temperature level in a single disk of the multi-disk brake. They take into account the time of contact pressure increase, convective cooling on lateral surfaces of the disk, and different thermal conductivity of material in the axial and radial directions. Calculations were performed for a disk made of carbon composite material Termar-ADF. The influence of the aforementioned input parameters on the temperature of the disk during single braking was studied. It is established that the obtained theoretical results are in good agreement with the corresponding experimental data.

“…To represent the imperfect contact condition in modelling studies of friction braking heat transfer, thermal contact conductance, hc (or thermal contact resistance, Rc) has been used. 12,22,23 Thermal contact conductance is not a material property and is not a constant. hc can vary depending on application conditions and is affected by many factors, such as contact pressure/load, sliding speed, contact temperatures, the material properties of the friction pair and the existence of an ITL.…”

A two-dimensional coupled temperature-displacement finite element 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 finite element 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.

A computational finite element model of a brake disc for determining transient axisymmetric (two-dimensional) temperature field during repeated brake application has been proposed. The presented research is a subsequent stage of a previous study on the coupling of velocity and maximum temperature for a single braking in accordance with the system of equations of heat dynamics of friction and wear. In the analysed case, changes in the mean, flash, maximum and bulk temperature of the disc were determined and discussed. The calculations were carried out at the temperaturedependent coefficient of friction, the thermophysical properties of cast-iron disc combined with cermet brake pads and the time-varying contact pressure. The obtained results were compared with the reference values from the braking simulation at constant operating parameters and independent of temperature properties of materials. It was shown that the maximum values of the mean temperature for both cases differed slightly during the entire process. The flash temperature determined from the heat dynamics of friction and wear system of equations was the highest at the beginning and gradually decreased with the number of brake applications.
