Critical aspects in obtaining accurate and consistent inertia properties are examined. These include a method of determining direction cosines for transducers utilizing sonic digitization, supplementation of estimated values with known parameters, scaling FRF matrices to force known parameter solutions, selection of consistent perimeter excitations, and weighting the approximated input and response rotations against the measured translations. Experimental examples are presented illustrating these critical aspects. 2004-10-06 English text University of Cincinnati / OhioLINK http://rave.ohiolink.edu/etdc/view?acc_num=ucin1093047356 http://rave.ohiolink.edu/etdc/view?acc_num=ucin1093047356 unrestricted This thesis or dissertation is protected by copyright: all rights reserved.
