The cold stamping forming processes of the car beam left/right section were designed and analyzed using the CAD/CAE technology and related software. Based on the establishment of the numerical model for the car beam left/right section, the stamping processes of the product were determined through the technical analysis. In particular, the effects of different drawing schemes and parameters (including blank-holder force, blank size, lubrication conditions, etc) on the manufacturability of the product were investigated by numerical simulation technology. The forming effects were evaluated according to forming limit diagram and thickness distribution diagram. As a result, the reasonable process design and optimum parameters are obtained, which can reduce the tendencies of wrinkling, cracking and thickness reduction, and achieve sufficient plastic deformation of the blank.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
