Abstract: The design objectives are determined based on the functional and performance requirements of the active return spring plate for automotive brake calipers. Core characteristic parameters are extracted using theoretical calculation formulas, and parametric modeling and simulation analysis are conducted in accordance with these characteristic parameters to output the target clamping force and active return force of the spring plate. The article completes the design of the spring plate following the design method, then manufactures prototypes and conducts simulation verification. It compares and analyzes the results of the prototype test simulation verification with the simulation results, optimizes the characteristic parameters, and finally summarizes and refines a design process method for the active return spring plate of automotive brake calipers. This process provides methodological support for the design of the key component (spring plate). By adopting the analytical method combining simulation and test, it realizes the parameterization of structural characteristics, provides technical support for suppressing brake abnormal noise and reducing drag, and is of great significance for the optimal design, performance improvement and reliability assurance of the spring plate.
