Abstract

In the stamping of industrial parts, friction and lubrication play a key role in achieving high quality products and reducing scrap. Especially in the start-up phase of new production runs, transient effects can have a significant impact on the product quality. Before a steady-state production run is established, heating up of tools influence tribological conditions. This influences the performance of the forming operation and, consequently, the quality of the formed product. In the development process of new industrial parts, it is therefore crucial to accurately account for these transient effects in sheet metal forming simulations. This paper presents the modeling of the frictional behavior of two tribological systems as developed within the ASPECT project. The first tribology systems consist of a stainless steel with corresponding drawing oil and tool material. The sheet material of the second tribology system is a hot dip galvanized bake hardened steel. Subsequently, it is shown how temperature affects the frictional behavior of these tribology systems. Finally, generated friction models have been applied to a spare wheel well of Opel. The spare wheel well is modelled using a generally applicable approach to account for transient effects under industrial sheet metal forming process conditions. For varying temperature and tribological conditions, the spare wheel well can show cracks and differences in thinning and draw-in. This emphasizes the strong influence of transient effects on both part quality and the overall production stability.
