> An accurate way of calculating accelerations about the head cg is by using
a
> firmly affixed headband with three tri-axial accelerometers mounted to it
> (one on the forehead and one above each ear). By using three different
> tri-axial accelerometers, placed and measured relative to bony landmarks,
> the head cg can be accurately calculated. Our firm has in the past and
> continues to conduct low-speed crash test biomechanical research with a
data
> acquisition system that can sample at 1,000,000 Hz. We also have a
> low-profile tri-axial accelerometer that can be affixed to other physical
> landmarks of interest (i.e. C7-T1, sternum, L/S, etc.) and another
tri-axial
> accelerometer that we bolt to the target vehicle. We are continually
adding
> accelerometers and channels to our data acquisition system. I would
> discourage you from using a bite block for measuring accelerations in
> low-speed rear-end collisions because it can introduce many different
types
> of error and more sophisticated ways of measuring head accelerations have
> already been employed by biomechanical researchers. If you have any other
> ideas, concerns, or thoughts about low-speed rear-end crash testing please
> feel free to contact me.
