Fatigue analysis with time series

Until now: Calculation with rain flow count and/or damage equivalent load range Until now, the temporal connection between affecting forces and torques and its occurrence was not considered. Only the statistic frequency of occurence was related to the material characteristics (Woehler line), as for instance with Rain-Flow-Count or damage equivalent load range.

New: Taking time series into consideration By using specially developed simulation and evaluation technology it is now possible to consider the connection between the different force and torque effects and their simultaneous occurence. Thus, much more precise information regarding material behaviour over longer periods of time can be given. This is particularly relevant if different forces and torques acting towards different directions occur at the same time and also variable, such as, for instance, with wind energy converters.

The advantages on one sight

• Temporal connection between the load components is kept up
• Calculation of the entire FE-model (i.e. via all notes)
• Optical presentation of the fatigue distribution inside the component
• Consideration of different materials (i.e. use of various Woehler-lines)
• Display of the stress variation ranges for welded constructions is possible
