Outline
This article provides an overview of the current research status and development trends of key technologies for brake discs. It primarily focuses on aspects such as temperature field control, fatigue life prediction, lightweight design, and brake noise control. Research indicates that by optimizing structures such as ventilation holes, heat dissipation rib layout, and surface grooves, combined with geometric parameter control, convective heat transfer efficiency can be significantly enhanced, temperature gradients effectively reduced, thermal stress peaks lowered, thermal deformation suppressed, the risk of thermal cracks reduced, and fatigue life improved. The introduction of optimization algorithms has facilitated the collaborative design of heat dissipation performance and structural strength. Through topological optimization, material distribution and shape optimization can be restructured, leading to significant weight reduction. Optimizing the vibration source or improving the thermodynamic characteristics can effectively suppress brake noise. In the future, the optimization of brake discs needs to consider the effects of dynamic thermal-mechanical coupling, cyclic mechanical vibration, and extreme operating conditions during actual braking processes.
