The effect of mass, stiffness and geometry on injury outcome in side impacts - a parametric study.
This paper reports on a cooperative research project between the Australian Department of Transport and Regional Services and Transport Canada. This project was a parametric study aimed at better understanding the effects on side impact injury risk of: * Trolley mass * Barrier stiffness * Barrier stiffness distribution * Barrier face height above ground * Crabbed or perpendicular impact * Impact Speed The following observations on injury risk can be made from the tests: * The 2 largest effects for the driver are increasing the height of the barrier face (mainly thoracic) and test speed (all body regions). * Increasing the trolley mass, with a bullet / target mass ratio less than 1, has the effect of increasing only the pubic force. * Doubling the barrier stiffness increases injury risk in only the pelvic area. * The custom high and stiff element (attempting to replicate an SUV) increases both pelvic and abdominal loading.
