Abstract: Aiming at automotive sliding door ride performance, the optimization was finished by using the orthogonal experimental design. While opening or closing sliding door, the middle sliding rail and armshafts displacements in axis X and Y were taken as optimization viriables, and the sliding door centriod traces merits were taken as design specification. Initially, the ranges of four optimization variables in their own directions were given while there was no occurrence of interference between sliding door and body in process of opening sliding door. Some orthogonal texts were done and sliding door centroid trajectory curves were caught. These traces curvature characteristics were compared. The results indicate that middle sliding rail and armshafts displacements have a significant impact on ride performance of automotive sliding door.
