Title: Active Members to Establish On-Orbit Modal Data for Modal Correlation
Authors: Wada, Ben K.
Kuo, C-P
Issue Date: 27-Jan-1994
Citation: Honolulu, HI
Abstract: The paper presents an approach to experimentally determine the modal sensitivity derivitives with respect to physical parameters of a structure in space or on the ground. The information experimentally validates the Jacobian used to update the analytical model to correlate with the experimental modal data. The approach is applicable to Adaptive Structures and utilizes active members. For verification of the approach, numerical simulations of a 4.5 meter diameter truss structure and experimental verification plan and progress are presented.
