An analytical model to determine temperature in a single brake disc of multi-disc system is proposed. The model considers the convective cooling on the lateral surfaces of the disc and structure of composite friction material. Calculations were carried out for a disc made of carbon friction composites material Termar-ADF. The influence of heat transfer with environment, length of bundles with fibers, and concentration of fibers in composite on the temperature of the disc was investigated during single braking with constant deceleration.

An analytical-numerical nonlinear model to investigate temperature fields and thermal stresses in a pad and a disk for a single braking with a constant deceleration has been proposed. For this purpose, the boundary-value heat conduction problem for a tribosystem strip-semi-space has been formulated, which takes into account the temperature dependence of the thermophysical properties of materials. The solution to this problem has been obtained by a partial linearization through the Kirchhoff substitution, and next with a subsequent use of the method of linearizing parameters. Knowing the distribution of temperature fields in the elements of a friction pair, the thermal stresses have been established within the theory of thermal bending of plates. In this case, the temperature dependence of the Young's modulus, Poisson's ratio, and linear thermal expansion of the pad and disk materials have been additionally taken into account. The numerical analysis has been performed for a friction pair consisting of a titanium alloy pad and a steel disk.

Disc brakes are the most widely used key components in the braking system of various types of machinery and equipment. When it works, it converts kinetic energy into thermal energy, which will make the braking interface overheat, thus leading to thermal recession of the brake disc and brake pad, which will eventually seriously affect the service life of the machine. The study of temperature changes at the working interface of disc brakes during braking is of great significance to the selection of brake friction pairs and the setting of braking parameters, and is an important theoretical guarantee for improving the service life of brakes. Currently, there are extensive researches on the analysis of temperature fields at the working interface of disc brakes. This paper summarizes the latest numerical research progress of the friction interface temperature field of disc brakes, and evaluates the research status of the friction interface temperature field model, temperature field solution method, and thermodynamics. The review finds that the current numerical method has become the most common method for conducting thermal analysis of disc brakes. The finite element analysis based on thermal modeling, thermal-mechanical coupling methods, and temperature distribution is able to provide more research basis for studying the thermal failure of brake friction pairs, thermal damage mechanisms, and friction material wear mechanisms. Improving the accuracy of the thermal model calculation will be an important research direction for the future numerical analysis of the temperature field of disc brakes.
