Accuracy and Repeatability of the Standard Automated Mass Properties MeasurementSystem

摘要

The injury potential to pilots may be significantly affected by the inertialproperties of helmet-mounted equipment. In order to accurately assess the effects of such equipment, reliable measurements of mass, center of mass, and mass moments of inertia must be obtained. The Manikin Testing Laboratory at the Armstrong Laboratory has developed the Standard Automated Mass Properties (STAMP) system to experimentally determine the inertial properties of various objects. It is necessary to quantitatively determine the accuracy and repeatability of measurements obtained by the STAMP system to confidently use these values in analytical models, in correlations between observed empirical response and the inertial properties of head-mounted equipment, and in determining compliance with inertial properties specifications of new helmet-mounted systems.
