Repeatability of Frontal Offset Crash Tests
Published May 31, 1998 by National Highway Traffic Safety Administration in United States
The Insurance Institute for Highway Safety publishes crashworthiness evaluations of passenger vehicles based on their performance in a 40 mi/h (64 km/h) frontal offset crash test. This paper describes the repeatability of vehicle and Hybrid III driver dummy responses for several pairs of vehicles in this type of crash test. Vehicle responses that were compared include interior intrusion measurements and vehicle accelerations. Driver dummy responses include dummy movement during the crash and electronic injury measures from the head, neck, chest, and upper and lower legs. The seven models that were tested twice are the 1997 Dodge Neon, 1997 Hyundai Elantra, 1994/95 Saab 900, 1995 Ford Taurus, 1997 Pontiac Trans Sport, 1996 Nissan Quest, and 1997 Infinite Q45. Structural measures in the repeated tests were similar to those in the first tests for most models. Among injury measures, head injury criteria, neck tensions, chest compressions, femur and tibia axial forces, upper tibias indices, and foot accelerations also were similar in the repeated tests for most models. Neck bending moments and lower tibia indices were less consistent. Implications of these comparisons for the Institute''s crashworthiness evaluations are discussed.
