Automated Mass Properties Measurement System Calibration Procedures
Abstract
This report describes the procedures used to calibrate the automated mass properties measurement system, a system consisting of various components that together measure the mass, center of mass location, magnitudes of the principal mass moments of inertia, and orientation of the principal axes of a given test object. This system, located at the Armstrong Aerospace Medical Research Laboratory, Wright-Patterson Air Force Base, can determine the mass properties of test objects weighing from 0.5 to 450 pounds. It is used for a variety of applications including measuring the properties of manikin segments for modeling purposes or evaluating newly developed helmets and night vision goggles to determine the effects of adding their mass to the head-neck system. As the system is actually composed of a number of devices that measure different aspects of the mass properties, each of these components must be calibrated separately. A description of the use of each component and the procedure used to calibrate it is presently for all of the devices. After each of these separate elements are calibrated, the accuracy of the entire system is then verified using an aluminum test block. The procedure described herein should be repeated at least once a month and before and after every test series.
