Application of computer modelling in part ,die ,and process design for manufacturing of automotive stampings

摘要

Recent studies in sheet metal forming ,conductedat universities world wide ,emphasize the development ofcomputer aided techniques for process simulation .To bepractical and acceptable in a production environment ,these codesmust be easy to use and allow relatively quick solutions .Often ,itis not necessary to make exact predictions but rather to establishthe influence of process variables upon part quality ,toolloads ,material flow ,and material thickness variation .Incooperation with its industrial partners ,the ERC for Net ShapeManufacturing at the Ohio State University has applied a numberof computer codes for analysis and design of sheet metal formingoperations .This paper gives a few selected examples taken fromautomotive applications and illustrates practical uses ofcomputer simulations to improve productivity and reduce tooldevelopment and manufacturing costs.
