NHTSA Testing Dynamic Rollover Test System Mimic dynamics of real world rollover crash Wide range of conditions Record information on vehicle kinematics, boundary conditions, and deformations
IIHS Testing Frontal Crash Moderate Overlap – 40% overlap impact Deformable barrier Small Overlap – 25% overlap impact Rigid Barrier 40 mph Forces recorded from dummies: neck, chest, legs, and feet
IIHS Testing Side Crash 3300 lb. striking barrier hits vehicle at 31 mph. Hits higher than NHTSA test Dummy records forces on head, neck, chest, abdomen, pelvis, and leg Dummy to represent small female or 12 year old is utilized
IIHS Testing Roof Strength Test Rollover Evaluation Steady Constant force applied to one side of roof at varying strength: weight ratios Peak Ratio of strength before deflection of 5 in. http: //www. iihs. org/iihs/ratings-info/roof-strength-test
