摘　　要：本文分析商用车车架纵梁成本要素与工艺特点之间的关系、工艺特点与设计参数之间的关系,从而找到成本要素与设计参数之间的函数关系,可以通过简单的设计参数输入,快速估算实物成本。本方法可应用于新车开发前期成本目标制定、开发过程中整车实物成本控制、零部件供应商价格谈判等;从而指导产品开发过程中整车及零部件的设计成本控制策略、零部件价格控制要点,达到成本正向设计的目的。This paper analyzes the relationship between the cost elements and process characteristics of commercial vehicle frame longitudinal beam and the relationship between process characteristics and design parameters, so as to find the functional relationship between cost elements and design parameters. Can be input through simple design parameters. Quickly estimate the physical cost. This method can be used to determine the predevelopment cost of the new vehicle, to control the physical cost of the whole vehicle and to negotiate the price of the component suppliers.
