Abstract
A new concept called Compatibility appeared in the field of automobile designs. Compatibility designs require to protect not only the safety of the own driver and passengers but also that of driver and passengers in another car at collision. There are not so many researches on compatibility design of cars and the performance indices to evaluate the compatibility have not been fully studied among them. In this study structural interaction problem between front strength members of mutual cars are of interest as one of significant problems. Five performance indices are shown and discussed through crash numerical simulations making use of detail FEM models. Then crash numerical simulations are carried out using two models and virtual barrier to measure the crash load distribution in stead of loadcells.
