Abstract:

NHTSA contracted EDAG, Inc., to re-examine feasibility of increasing seat back strength by developing a detailed finite-element (FE) model of a current vehicle front seat design that can be used with existing anthropomorphic test dummy (ATD) models of the Biofidelic rear impact dummy (Bio-RID) to study seat performance in rear impact crashes. The results from this task order are the finite-element models of a 2014 Honda Accord mid-size sedan representing typical front seats. There are two front seat models that have been developed using LS-DYNA simulation code. One is a manually operated seat and the other is a power operated seat , both capable of simulating occupant kinematics and injury performance measures in rear impact in a longitudinal direction, and capable of responding to incremental impulses spanning from 17 km/hr. up to 40 km/hr.
