Problems of Measurement in Human Analog Research.
Abstract
The Naval Biodynamics Laboratory in New Orleans is involved in a continuing effort to describe the kinematic and physiological response of anatomical segments of human volunteers to acceleration environments. The scope of this presentation is to discuss some of the problems that arise in the measurement of the three dimensional dynamic response of human volunteers to relatively short duration (250 millisecond) acceleration profiles. With pre-selection of accelerometers and careful calibration procedures six accelerometer configurations can provide results which agree well with photo-derived results at the velocity level in the time window of interest (250 milliseconds) for the acceleration profiles. With pre-selection of accelerometers and careful calibration procedures six accelerometer configurations can provide results which agree well with photo-derived results of the velocity level in the time window of interest (250 milliseconds) for the acceleration profiles investigated at the NBDL. Accelerometer-derived kinematic variables are best at the acceleration level and photo-derived variables are best at the displacement level and thought should be given to combining results of these two measuring systems into one consistent set of kinematic variables from the acceleration to the displacement level.
