Subproject C5

Variable processes and application of methods and technologies for uncertainty control in load-carrying systems

The subproject C5 emphasizes on two research issues.

The first issue is to evaluate, which functional relations of different mathematical models based on their complexity and scope predict the dynamic behavior of the SFB-Demonstrator and its modular components on the one hand and the resulting existence of model uncertainty including the quantified uncertainty with confidence limits on the other hand. The second issue is to find suitable passive, semi-active and active measures that contribute towards the control of quantified as well as unknown data and model uncertainties, which prevail during the production and the usage phases of the SFB-Demonstrator that also represents the different types of load-carrying systems.

Prediction of the dynamic behavior of the modular active spring-damper system MAFDS (German acronym) by means of axiomatic and empiric mathematical models as well as performing experimental tests on MAFDS
