Computational Modeling of Torque Arm and Load Cell Interactions in UTA Racing Brake Dynamometer
An honors capstone analyzing torque arm and load cell interactions in a brake dynamometer used for FSAE friction testing.
This honors capstone paper presents computational modeling of the torque arm and load cell interactions in the UTA Racing brake dynamometer. The work supported a tabletop dynamometer capable of measuring brake pad friction up to 1300°F, integrating an 8-channel IR temperature sensor, K-type thermocouples, a compression load cell, and a 2000-psi pressure transducer. The modeling informed the design of a brake-pressure actuator using a 10:1 lever ratio to amplify 34 lbf to 335 lbf, reaching brake pressures up to 879 psi.
