Abstract:The transverse bowing greatly affects accuracy of the roll forming asymmetric corrugated channels (ACC). In order to control this defect, the paper first elucidates its mechanism of the production. Then the transverse bowing is explored by finite element method (FEM) using ABAQUS 2016 software and the effects of the forming parameters are analyzed. Also, a linear regression model is built using Minitab 19 software to evaluate their effects, of which standard values are measured by Pareto chart. It is observed … Show more
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.
