Aim of the project is the development of tailored tribological systems, for example by the adaption of the geometry of workpiece- and tool-sided lubricant pockets. In order to numerically analyse the tribological conditions, the constitutive friction law will be linked to the FEM. Additionally, the behav-iour of tailored tribological systems along the production time will be numerically and experimentally investigated. To identify the functioning of the different tribological measures, the experimental and numerical methods are comprehensively used. Based on these results, generalizable knowledge for the application of tailored tribological systems in sheet-bulk metal forming is derived.

该项目的目标是开发定制的摩擦学系统，例如通过调整工件和刀具侧润滑剂腔的几何形状。为了对摩擦条件进行数值分析，本构摩擦定律将与有限元法联系起来。此外，还将对定制摩擦学系统在生产过程中的行为进行数值和实验研究。为了确定不同摩擦学措施的功能，综合使用了实验和数值方法。基于这些结果，得出了在板状金属成形中应用定制摩擦学系统的通用知识。
