Stamping of automotive components: a numerical and experimental investigation

Stamping of automotive components is a critical activity characterized by short lead times and constant technological modifications in order to improve quality and reduce manufacturing costs. Virtual manufacturing of automotive stamped components by means of finite element computer analysis is a powerful tool that can help engineers solving different technological problems. This paper presents applications of finite element analysis on the re-evaluation of the performance of tooling after changing the raw material (conventional to a high strength steel), as well as on the debugging of undesirable manufacturing occurrences. The investigation was performed during the industrial try-out of two automotive stamped parts; a rear seat and a structural reinforcement. The work is supported by experimental observations and selected data measurements.
