Robust Design of Energy-Absorbing Crumple-Zone Structures Considering Uncertainties
Development of a new, fuzzy arithmetical design strategy for an optimized energy-absorbing automotive crumple-zone structure with robustness against both aleatoric and epistemic uncertainty
The crumple-zone structure to be optimized with respect to the absorbed kinetic energy shall be represented by a model with uncertain, fuzzy-valued parameters which is capable of representing the
aleatory uncertainty due to unpredictable crash conditions and the
epistemic uncertainty due to simplification, idealization and reduction of the full-scale car model
Due to the numerous simplification techniques for the full-scale car model, different fuzzy-parameterized models for the crumple zone can be derived
The fuzzy-valued parameters need to be identified on the basis of crash simulation data using inverse fuzzy arithmetical strategies
Model quality assessment and selection of the “best simplified, fuzzy-parameterized model” will be important
Optimization in the presence of fuzzy-valued uncertainty needs to be performed (constraints may be met or violated in a fuzzy manner, …)
