Design of the Brake System and Brake Force Optimization Based on MATLAB

The FSAE brake system is a hydraulic dual-circuit system that maintains a constant braking force distribution coefficient. This paper focuses on designing various parameters of the braking system, including the braking force distribution coefficient, in accordance with competition regulations. By analyzing the braking system and employing a simplified model of the racing car, multiple parameters are devised. Utilizing MATLAB’s Fmicon optimization function and incorporating suspension characteristic parameters, this method optimizes the braking force distribution coefficient. The aim is to achieve a braking efficiency exceeding 80% under a road adhesion coefficient of approximately 1. The obtained results guide the selection of an appropriate brake master cylinder, brake caliper, and other essential parameters, culminating in the determination of maximum braking deceleration and braking distance.
