SEVERITY INDEX FOR VEHICLE DRIVERS AT FRONTAL IMPACT INTO RIGID BARRIER

Abstract

This article deals mainly with frontal impacts of vehicles of various classes (small cars, middle class, Pickups/SUVs, etc.) into a fixed barrier according to the NHTC (National Car Traffic Safety Administration) for the US-NCAP (New Car Assessment Program). The acceleration record was processed from the accelerometer through the Logger Pro program package. If the accelerometer was firmly connected from the car's rear floor, the deformation path (maximum deformation) or plastic deformation was calculated. If the accelerometer was firmly connected from the manikin's head, the severity index (SI index) was calculated to increase the active and passive safety of the passengers
