Structural analysis techniques are now available that allow the development of safer vehicle structures. The basis for the development strategy is new knowledge of the biomechanics of injury and of the spectra of real life accidents occurring in Australia, plus new computer simulation techniques. An optimised crash pulse is proposed, which analysis suggests will provide reduced injury risk throughout the spectrum of frontal crashes. Design of a vehicle with a front structure having this characteristic could result in reduced injury risk to occupants in the complex interaction between the occupants and the vehicle during the variety of crash types and speeds that occur on Australian roads.
