This article presents the design, modeling, and simulation analysis of electronic mechanical brakes. Firstly, the design of the electronic mechanical brakes motor, planetary gear reducer, and ball screw is based on the vehicle parameters. CATIA is used for three-dimensional modeling of the components of the electronic mechanical brakes. Subsequently, transient dynamic simulations of the brake disc and brake pads are conducted using ANSYS/Workbench to validate the effectiveness of the model and the stability of the braking performance. The modeling and simulation of this study provide strong theoretical support and technical reference for the performance improvement and optimization design of electronic mechanical brakes, which will help promote their widespread application in the automotive and related fields.展开更多
