The weatherstrip is one of the main factors affecting side door closing efforts. Primary and the secondary seals are the major contributor to door closing efforts. This paper study the effect of the manufacture variation for the compresses load deflection (CLD) for the weather strips on side door closing efforts and the manufacture variation of the seal gap too. The seal gap will be divided into segments to analyze the effect of each segment individually. The goal of this study is to optimize the closing effort by optimizing the seal gap variation for the secondary seal and optimize the manufacture tolerance for the primary and the secondary seals CLDs. Also, identify which seal segment is the main contributor to side door closing effort. These results are particularly helpful in developing and optimizing weather strip designs by computing efforts toward door-seal designs.
