Abstract： To address the issue of brake disc overheating during emergency braking in Formula Student Autonomous China （FSAC）racing cars，which impairs braking performance and shortens disc lifespan，a structural optimization scheme featuring a slanted vent structure is proposed. ANSYS finite element analysis was conducted to compare the temperatures of brake discs with cooling vents angled at 60∘ ， 70∘ ， 80∘ ，and 90∘ relative to the disc plane. Simulations demonstrate that 70∘ -angled vents reduce peak braking temperatures by about 6 C compared to conventional 90∘ straight vents，effectively mitigating brake fade while enhancing efciency and longevity.Track testing validated the simulation results，confirming structural efficacy.This design provides a reference for brake disc design in other racing teams.
