Rule and optimization-based selection of car body parts for the application of tailor rolled blank technology

Abstract The majority of parts in modern car bodies is manufactured from sheet metal. Rarely these are fully stressed due to design space restrictions and complex requirements. usage tailor rolled blanks (TRB) enables the reduction thickness areas less loaded thus reduces part weight. Technically most metal potentially suited for application TRB. Economic circumstances like additional flexible rolling process technology-specific nesting constraints limit a subset parts. search best candidate taking mass cost into account currently challenging. This article presents an optimization strategy selection vehicle structure that As first step, priori preferencing performed select based on engineering rules. Using reduced number parts, high quality metamodels trained perform multiobjective optimizations all possible combinations remaining revealing efficient under consideration cost.
