Abstract: The NHTSA frontal 90 kph 150 OMDB 35% offset test is a part of the new test protocol being proposed to simulate small overlap and oblique impact crashes in the field. An advanced crash test dummy, THOR, is proposed in the test protocol for injury risk assessment instead of the standard frontal impact dummy Hybrid III (H-III). An integrated vehicle finite element model with H-III, THOR and the GHBMC 50th male models is employed to compare the kinematics and injury differences. In this study, we evaluated the occupant response in the new frontal OMDB test using GHBMC models to quantify and qualify the potential injury pattern and risk in this type of crash. The vehicle model was validated with both a full frontal 35 mph rigid barrier test and the very first frontal OMDB test with the H-III 50th %ile male dummies is conducted. The differences in the measured responses of the H-III and THOR from simulations and tests, and the simulated responses of the GHBMC model, were compared. The additional tissue-level injuries predicted by the GMBMC model, which are beyond the capability of the H-III and THOR dummies, showed the potential injury pattern and risk of occupants in the OMDB test.
