Setting method of metal sheet anisotropy information and sheet thickness information for analysis model of press-formed panel, and stiffness analyzing method

摘要

A method of setting metal sheet anisotropy information and sheet thickness information for an analysis model of a press-formed panel includes spreading the analysis model of the press-formed panel into a blank shape by analysis of reverse press-forming; acquiring sheet thickness information obtained by the analysis of reverse press-forming; based on a spread-blank-shape and a panel-taking blank shape, acquiring a reference direction of the spread-blank-shape; calculating an angle formed between the reference direction of the spread-blank-shape and each element in the spread-blank-shape, and setting the reference direction for each element of the analysis model of the press-formed panel based on the calculated angle; and setting the sheet thickness information acquired in the sheet-thickness-information acquiring step for each element of the analysis model of the press-formed panel.
