Digital Environmental Data Analysis and Usage Modeling for Vehicle Durability

[Die Veranstaltung ist nur in Englisch verfügbar.]

The design and assessment of vehicle components with respect to durability and reliability starts with the description and modeling of the usage variability, which arises due to the combination of different mission profiles or driver behaviour and the varying environmental conditions in different regions of the world. Accordingly, the loads vary considerably and a proper statistical modeling is required. The next step is to derive reference loads which are used within the development process and fundamental for release tests. To this end, measured data is analysed and extrapolated to a given design life based on the classification of factor models (which type of load cases are relevant) and the application of usage models (how often do these load cases occur in a certain customer group). High quantiles of the corresponding distributions are used to define the reference loads.
