Side Impact Modelling Using Lumped Mass and CAL-3D CVS Simulations 840859

Experimental research to improve protection levels offered to automobile occupants in lateral collisions has focused on the study of responses of the 50th percentile male as a result of the availability of the Side Impact Dummy of that size. The question of the suitability of protective measures developed for the 50th percentile male for the other occupant sizes is of concern. Hence, a major objective of this study was to analytically evaluate injury potential of a broad range of occupant sizes in lateral collisions in combination with various types of padding.
Two computer models were used in the study. The first was a one-dimensional lumped mass model. The CAL-3D crash victim simulation was also configured to represent an occupant in a lateral collision with intruding door motion.
Results of the study indicate that padding on the interior of the door surface is beneficial to all occupant sizes.
