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.

“…torque [30][31][32][33][34]. In particular, when used as a braking device, the heat of the device will cause the temperature to rise severely, which may lead to the permanent demagnetization of the PM; so, it is necessary to model the thermal field to facilitate the design of heat dissipation [35][36][37]. Therefore, the study of PMECCs is a typical multi-field coupling problem.…”

Permanent magnet eddy current couplers (PMECCs) have the characteristics of contactless torque transmission, removal of torque ripple, smooth dynamic process, and adjustable speed, and can be used as couplings, dampers, brakes, and speed governors. Their applications in industry, vehicles, and energy fields are gradually expanding. At the same time, the requirements for the torque density and dynamic performance of PMECCs are increasing. Therefore, a large amount of research work has focused on the fast and accurate modeling, design, and optimization of PMECCs. This paper provides a survey on the development of PMECCs technology. The main topics include the structure and classification of PMECCs, modeling methods, loss and heat transfer analysis modeling, and optimization design. In addition, this paper shows the future trends of PMECCs research. All the highlighted insights and suggestions of this review will hopefully lead to increasing efforts toward the model’s construction and the optimal design of PMECCs for future applications.

“…In addition, solid steels with magnetic and electrical properties are used in ECBs, particularly in axial-flux-type industrial products [10], [11]. Recent research on ECBs [25] has introduced a new fast calculation method for the braking torque and temperatures of ECBs. Permanent magnets (PMs) or excitation coils can be used as the magnetic field source in ECBs.…”
