Abstract

Two new World SID (50th and 5th) FE models were developed for providing virtual tools of predicting occupant injuries during vehicle side collisions. The virtual dummy models have been verified with their physical counterparts in aspects of lab certification tests, bio-fidelity and sled tests. Many new techniques have been utilized in the model development including advanced testing and material modeling which guaranteed the high fidelity between the virtual models and the physical dummies. The good model-to-test correlations of various loading configurations have shown that the new FE models could be used as new tools in virtual simulations of vehicle side impact crash worthiness studies as options to other side impact dummies to predict better occupant injury due to superior bio-fidelity performances of the World SID dummies. The new dummy models were also tested under vehicle FMVSS214 impact conditions. A comparison of occupant injury parameters extracted from the models between the World SID 5th and SID-IIs dummy were also made using the load case.
