Abstract: The key design technology for the automotive sunroof localization and development is designed and studied. First the structure and working principle of the automobile sunroof are analyzed, then the 3D model is built by using reverse engineering, and virtual assembling is done with the virtual prototype. The design method of the motion mechanism of the automobile sunroof is simulated by the analytical software called ADAMS. The key parameters that influence the motion mechanism of the sunroof are emphatically analyzed, and design methods are studied based on the motion principle. Optimization design is carried out for the motion mechanism based on the simulation. The physical prototype is produced according to the simulation analysis and the optimization results. The motion test shows that the motion mechanism presented above can satisfy various requirements of the automobile sunroof, and also can lay the foundation for building the independent development platform of the automotive sunroof.
