FSAE SINGLE SEATER RACE CAR DISC BRAKE NUMERICAL THERMAL ANALYSIS: A CASE STUDY
Resumo
Brake system design is a significant part of one-seated race car design for SAE Formula student competition. Car brakes should not only be strong enough to deal with the massive mechanical loading, but also should dissipate the generated heat in order to keep the maximum temperature below the critical values preventing failure due to brake fade, thermal stress and thermo-mechanical fatigue. Moreover, weight of the brake discs is of vital importance contributing to the total weight and vehicle performance. This paper provides a methodological study to analyze the temperature profile for a disc brake rotor under intermittent loads during sequential braking and acceleration/cruising events. A time dependent vehicle speed and braking intensity profile is generated using "OptimumLap" software for default FSAE vehicle and 2019 FSAE competition Lincoln endurance track. "SolidWorks" thermal analysis is used to simulate the temperature distribution of the brake disc after series of consecutive braking and acceleration/cruising events (over 200) in multiple laps. This study involves a realistic methodology for the analyzing disc brake temperature profile for FSAE race cars.
