Crash Brackets Development for ECE R29

Andrea Morello, Marco Barbi (IVECO)

This work shows the main steps done in the development phase of IVECO cabin suspension brackets in order to be compliant with new crash regulation ECE-R29 for Heavy Commercial Vehicles.

In this activity modeFRONTIER leads and drives different CAE software (Hypermesh, Radioss, Nastran and Matlab) in order to fulfill all the targets on the part in exams. Indeed, this element must behave like a crash box, it means big deformation and plasticization in case of a crash event, while in the meantime it must be enough strength in order to survive the IVECO fatigue mission without failure. These are two typical opposite targets, a good challenge for modeFRONTIER.
