The latest publication of the KTmfk with the project partners from Hamburg (LaFT) and Karlsruhe (IPEK) was selected as the cover story for the March issue of the journal Applied Sciences. The publication addresses a co-simulation model consisting of a musculoskeletal human model, an exoskeleton mode...

For sampling-based tolerance-cost optimization, a high number of function evaluations is unavoidable, which can lead to long calculation times. To overcome this shortcoming, the latest KTmfk publication presents an innovative strategy that combines metaheuristic optimization and adaptive surrogate m...

The use of system models in the context of model-based system engineering (MBSE) is essential for improved communication and system documentation. However, publications in recent years show that efforts are also being made to reuse these system models e.g., by converting them directly into disciplin...

The 24th International Colloquium Tribology took place from January 23 to 25 in Ostfildern. In 130 presentations and numerous plenary lectures, national and international research results on a wide range of tribology topics were presented. The KTmfk was represented by Klara Feile and Benedict Rotham...

KTmfk researchers Christian Witzgall and Sandro Wartzack, in collaboration with visiting professor Moh'd Sami Ashhab, present a novel strategy for fatigue testing of short fibre reinforced thermoplastics in the journal Materials. Using adaptive sampling and artificial neural networks (ANNs), the stu...

Small and medium-sized enterprises (SMEs) face the challenge of optimising their development processes through the use of data-driven methods. These methods can lead to more efficient and higher quality product development. PADDME (Process Analysis for Digital Development in Mechanical Engineering) ...

Unavoidable geometric variations are limited explicitly by geometrical and dimensional tolerances to ensure that technical systems fulfill their function despite manufacturing inaccuracies. However, in doing so, the requirements for the subsequent manufacturing and, thus, the costs are implicitly se...

On 29th of November this year's Munich Symposium on Lightweight Design took place at the TUM in Munich with a focus on optimization and additive manufacturing. Stephan Freitag represented the KTmfk and gave a presentation on the continuous and optimal design and layout of fiber-reinforced structures...

A new KTmfk paper deals with the fatigue damage of components made from short fibre-reinforced thermoplastics. These are damaged by repeated loading, which leads to a significant deterioration of the mechanical properties. The method presented by Witzgall and Wartzack enables a realistic simulation ...

The German chapter of the INCOSE (GfSE) hosted the “Day of Systems Engineering” from November 15 – 17, 2023 in Würzburg. Simon Schleifer represented the KTmfk and gave a presentation entitled “Potential analysis of SysML-based modelling of systems and processes in the context of tolerance management...
