Abstract: The optimization design of a certain car's braking system based on the vehicle matching aims to simplify the brake design process while meeting relevant regulations. By integrating the vehicle performance parameters with the design of disc brakes, a design strategy for disc brakes is formulated. Through calculations of the maximum braking torque on each wheel during the braking process and selecting the synchronous adhesion coefficient for the car, the key design parameters and materials for the main components of the disc brakes are determined and verified to comply with the requirements of relevant regulations. Finally, computer aided design (CAD) and UG software are utilized to complete the drawing of main parts and three-dimensional modeling. This optimized the design process of automotive brakes while meeting the requirements of relevant regulations, and lays the foundation for subsequent research on brake noise and other issues.
