The model of the operating mechanism assembly of parking brake is built with software UG, and the finite element model is obtained by importing it into ANSYS software. The accuracy of the finite element model is verified by modal vibration testing. According to the simulation results, the stress and strain distribution and weight optimization value of the main components are both analyzed. Finally, the assembly is conducted topology optimization, the optimization program is established after manufacturing treatment. The results indicate that the optimization of the operating mechanism assembly of parking brake meets the requirements of strength and stiffness, and the weight of assembly decreases by 33.8%.
