| Title: | Geometrias de referencia experimental en procesos de conformación plástica de chapas y su modelación numérica |
| Issue Date: | 2006 |
| Abstract: | This paper presents experimental reference geometries to be used in sheet metal forming. Eachreference geometry attempts to model the typical behavior of pieces of sheet metal. The results of thisstudy were compared with data obtained fram the literature. Discussion is also presented on aspectsrelated to the reproducibility and reliability of the results. Sliding of the blank over the punch, and thepress ram speed are important in this reproducibility. Finally, numerical simulations are presented forone of the reference geometries presented, using finite elements. The results are compared withexperimental results, demonstrating good correlation between them. |
| Description: | Este articulo presenta geometrias de referencia experimentales para ser usadas en procesos deestampado de chapas metalicas. Cada geometria de referencia pretende modelar un comportamientotfpico de piezas de chapa metalica. Se han comparado los resultados de este trabajo con otrospresentados en la literatura. Tambien se discuten los aspectos relacionados con la reproducibilidad yfiabilidad de esos resultados. El resbalamiento sabre el punz6n y la velocidad de la prensa son dosvariables que tienen un efecto importante en esta reproducibilidad. Finalmente se presentansimulaciones numericas de una de las geometrias de referencia presentadas usando elementosfinitos. Los resultados se comparan con valores experimentales y se muestra que hay una buenacorrelaci6n entre ellos. |
