These requirements are interpretable as constraints of a kind of “fatigue test optimization”. Reproduction of the results of the “full” fatigue test is the main objective of this optimization task.

FATIGUE DESIGN 2021, 9th Edition of the International Conference on Fatigue Design Definition of simplified fatigue tests using numerical optimization Prof. Dr.-Ing. Ronald Schrank* IAMT Engineering GmbH & Co KG, Ludwigsfelde, Germany Abstract “Virtual prototyping” has been established as an important part of the development process for technical components and techn ical systems. Fatigue simulation is a main discipline in virtual prototyping, but it is a quite complex field, especially for structures being exposed to time-varying multi-channel loads. Thus, at the end of the development process, the series approval for technical components is often based on extensive fatigue tests, particularly with regard to automotive chassis parts.

Currently, test-based fatigue qualification gathers interest in other process phases, for instance • to assure fatigue safety just for non-series / prototype parts • to make quality checks during series parts production on the supplier’s site • to validate fatigue simulation methods just within the first phases of the development process Currently, test-based fatigue qualification gathers inte est in ther process hases, for instance t assure fatigue safety just for non-series / prototype parts • to make quality checks during series parts production on the supplier’s site • to validate fatigue simulation methods just within the first phases of the d velopment proces
