ACTIVE MEMBERS TO ESTABLISH ON-ORBIT MODAL DATA FOR MODAL ADJUSTMENTS

摘要

The paper presents an approach to experimentally determine the modal sensitivity derivatives with respect to physical parameters of a structure. The experimentally determined Jacobian is used to adjust the modal characteristics of the hardware to match the desired modal characteristics. The approach is applicable to Adaptive Structures and utilizes active members. Numerical simulations of a 4.5 meter diameter truss structure and experimental verification plan and progress are presented.
