Abstract: This paper discusses the factors which affecting sedan BIW weight, including gross vehicle weight, BIW torsional stiffness, length, width, height and other dimensions. It finds out the key factors affecting sedan BIW weight through best subset regression analysis. Based on multiple linear regression analysis, this paper studied the relationship between the optimal influencing factors and sedan BIW weight. Then deduces a method for setting sedan BIW weight target, which provides an important reference for the development and setting of BIW weight target in the project development process.
