Design of car braking system based on Baja

Tang Xinghua，Liu Zhanzhao

Abstract：Based on the premise of meeting the rules of Baja Race， taking Z14 Baja racing car as the research object， using UG for three-dimensional modeling， ANSYS for brake pedal topology optimization is studied， designing a lightweight optimal braking system with reasonable parts assembly， braking force before and after self-adjustment. The designed brake pedal is 190G， providing a reference for the design of racing car.

Key words：topology optimization， reasonable assembly， braking system， UG
