The Effect of Mass, Stiffness and Geometry on Injury Outcome in Side Impacts - a Parametric Study 2000-01-SC01
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;
and 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.
