Abstract:This report describes finite element modeling to develop computational models of rear-impact semi-trailer guards used to simulate quasi-static tests prescribed by FMVSS No. 223 tests as well as a motor vehicle crash into the rear of a truck semi-trailer. For the crash simulations, existing FE models of passenger cars were applied, along with models of two 50th percentile male representations, the THOR-50M and the Global Human Body Models Consortium M50-OS model. Three rear-impact guard designs were modelled.
