轿车白车身重量目标设定方法

Weight Target Setting Method for Sedan BIW

文章探讨了影响轿车白车身重量的因素,包括总质量,车身扭转刚度,长、宽、高等尺寸参数,并通过最佳子集回归分析找到影响轿车白车身主要因素。最后,基于多元线性回归分析,研究最佳影响因素与白车身重量间的关系,并推导出一种用于轿车白车身重量目标设定方法,为项目研发过程中车身重量目标的开发设定提供重要参考。

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.
