| Résumé : |
The development of automotive components is governed by many criteria related to energy, materials and cost issues, as well as environmental requirements. These complex problems lead to the need for reliable simulation technologies to improve forming prediction and optimize complex assembled lightweight components using fiber-reinforced thermoplastic materials. During the first step of the investigation described in this paper, the developed simulation approach is shown to be able to determinate the optimum blank geometry for the manufacturing of parts, which leads to the best match with the designed part geometry. Finally, the adopted simulation method has shown its ability to perform virtual optimization of composite components. |
