“…To ensure the braking efficiency, the maximum surface temperature should be no larger than 662.3°C. The brake vibration mainly appears with a low-frequency band, 1 which means the natural frequency should be increased to avoid the brake shaking and chattering frequency.…”

The brake disc plays a crucial role to keep the stable braking of a high-speed and heavy-duty disc brake. There is always high temperature, brake vibration, and even serious deformation under braking pressure and frictional resistance. To improve brake performance, this paper aims to find new internal and surface structures of the brake disc. An equivalent moving load (EML) topology optimization method for internal structure is proposed. Topography optimization method oriented to displacement and stress control for surface structure is carried out. Multiobjective functions containing thermal-structural coupled rigidity and natural frequency of the brake disc are established in the internal and surface structure optimizations. Internal and surface structures of the brake disc are optimized, and the mechanic properties of the brake disc are improved. Thermal-structural coupling and modal analyses are verified with high-speed and heavy-duty brake working conditions. The results show that new brake disc structures meet the requirements, and the effectiveness of the proposed EML topology optimization and topography optimization methods has been proved.

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.

Struct Multidisc Optim

Multi-objective topology optimisation problems are often tackled by compromising the cost functions according to the designer’s knowledge. Such an approach however has clear limitations and usually requires information which especially at the preliminary design stage could be unavailable. This paper proposes an alternative multi-objective approach for the generation of minimal Pareto sets in combination with density-based topology optimisation. Optimised solutions are generated integrating a recently revised method for a posteriori articulation of preferences with the Method of Moving Asymptotes. The methodology is first tested on an academic two-dimensional structure and eventually employed to optimise a full-scale aerospace structure with the support of the commercial software Altair OptiStructⓇ. For the academic benchmark, the optimised layouts with respect to static and dynamic objectives are visualised on the Pareto frontier and reported with the corresponding density distribution. Results show a progressive and consistent transition between the two extreme single-objective layouts and confirm that the minimum number of evaluations was required to fill the smart Pareto front. The multi-objective strategy is then coupled with Altair OptiStruct and used to optimise a full-scale wing box, with the clear purpose to fill a gap in multi-objective topology optimisation applied to the wing primary structure. The proposed methodology proved that it can generate efficiently non-dominated optimised configurations, at a computational cost that is mainly driven by the model complexity. This strategy is particularly indicated for the preliminary design phase, as it releases the designer from the burden to assign preferences. Furthermore, the ease of integration into a commercial design tool makes it available for industrial applications.
