Abstract: Based on the topology optimization method, the optimization design of the floating caliper disc brake caliper body of a passenger car was carried out by using the finite element simulation analysis technology. The optimization design determines the optimal topology structure to meet the requirements of the development of the floating caliper disc brake caliper body of a new passenger car. The optimized design ensures the reliability of the caliper body of the floating caliper disc brake of the passenger car in the use process. The optimization design provides a theoretical basis for the lightweight development of the caliper body of the floating caliper disc brake of passenger cars. The results show that the center deformation of the piston chamber cylinder hole is 0.158 mm, and the maximum tensile stress is 370.2 MPa, which meets the design requirements of deformation and stress.
