Application of LS-DYNA and MADYMO Coupled Model for Simulating an Offset Frontal Crash Scenario

A full vehicle finite element model of the 1995 Chevrolet Lumina validated in full frontal impact was used to simulate a frontal offset impact. The tibia index injury criteria set forth in the European Directive 96/79 were used to assess the injury indices of the occupant in frontal offset computer simulation. Based on the injury predictions from the baseline model, a structural modification to vehicle was made in order to reduce the tibia index. In the modified vehicle model simulation, the tibia index of the occupant was found to be reduced from 1.13 to 0.73 for the right tibia and from 0.62 to 0.45 for the left tibia.
