| Title | Design and Thermal Flow Analysis of Ventilated Brake Rotors | ||
| Keyword | |||
| Abstract | This study investigates how different rib geometries in ventilated brake rotors affect heat transfer and structural responses, particularly under transient braking conditions. Five rib types¡Xstraight, straight half-length, scattered-post type, arc-shaped, and involute-curved¡Xwere modeled in 3D and evaluated through steady-state thermal simulations. Results show that arc-shaped and involute-curved ribs, with their curved or spiral features, significantly improve airflow penetration and heat flux uniformity. A two-way fluid¡Vstructure interaction (FSI) framework was then developed by coupling ANSYS Fluent and ANSYS Transient Thermal to analyze the straight and involute-curved ribs under transient conditions. The involute design exhibited superior heat diffusion and temperature uniformity, reducing local thermal concentrations and enhancing structural stability. In contrast, the straight rib, though easy to manufacture, had weaker cooling performance under high loads. Based on the simulation results, a general evaluation framework and procedure were established to guide future rib geometry design and thermal analysis for ventilated brake rotors. |
