This paper presents procedures for automobile structure design to reduce head injury of pedestians struck by the vehicle. The fender and hood seam of a 1988 Ford Taurus are modified to absorb the energy of a head impact. Two shape related design parameters are optimized for minimum Head Injury Criterion using finite element simulations. A design is presented which reduces Head Injury Criterion by over 50 percent. All analyses are conducted using the explicit, nonlinear, dynamic finite element code DYNA3D on a Cray YMP/832 supercomputer.
