Development of simulation model of an ODB
2007 (English)Independent thesis Advanced level (professional degree), 20 credits / 30 HE creditsStudent thesis
Abstract [en]

This thesis describes the development of a simulation model of the Offset Deformable Barrier, ODB. The barrier is used in Euro NCAP’s frontal offset crash test and mainly consists of a hexagonal aluminium cellular solid called honeycomb. The main object was to create a material model in LS-DYNA representing the material characteristics of honeycomb. The honeycomb structure is mainly used in energy absorbing lightweight structural components because of its high-energy absorption properties and high strength-to-weight ratio. The orthotropic nature of the honeycomb demands extensive material testing to be fully described in LS-DYNA An ODB manufactured by a supplier to Euro NCAP was purchased and physical crash testing in Gestamp Hardtech’s crash test facility has been used to ensure that the simulation model correlates with reality, regarding to force vs. intrusion. A simulation model of the Offset Deformable Barrier was successfully developed. The simulation model showed good correlation to the physical tests. The simulation model will later on be used to evaluate the performance of different bumper designs at Gestamp Hardtech, Luleå.
