THE NEW CAR ASSESSMENT PROGRAM: HAS IT LED TO STIFFER LIGHT TRUCKS AND VANS OVER THE YEARS?

In the New Car Assessment Program (NCAP) frontal crash tests, vehicles are crashed at 35 mph such that the entire front impacts against a rigid, fixed barrier. Instrumented anthropometric dummies are placed in the driver and right front passenger seats. Accelerometers are placed on the vehicle to record the response of the structure during the crash. In this paper, the acceleration data from accelerometers in the occupant compartment and from the dummies are analyzed to determine: (1) the trend of total stiffness or aggressivity characteristics of light trucks and vans (LTVs) since model year 1983; (2) the trend of the approximate linear stiffness of LTVs during the first 200 mm of crush since model year 1983; and (3) the effect of these structural characteristics on the NCAP safety ratings.
