Paper Abstract

The Naval Biodynamics Laboratory in New Orleans is engaged in a series of experiments to measure the dynamic response of critical segments of the human anatomy to acceleration environments. A configuration of accelerometers and photographic targets is mounted on a T-plate which is fixed to the anatomical segment to be measured. The kinematic variables defining the linear displacement and angular orientation of the rigid body are derived independently from the accelerometer and photographic measurements. This paper illustrates an optimum procedure for combining the results from both sets of measurements into one consistent set of derived variables from acceleration to displacement. The method is applicable to non-contiguous photo-derived variables and allows for the high frequency resolution capabilities of the accelerometer system while discriminating against low frequency errors in these components. The method used and examples comparing the photo-derived variables, the accelerometer-derived variables, and the combination variables for actual data obtained at NBDL will be presented.
