Paper Abstract

This paper explains the reason for the significant difference of payload responses when different damping methods are applied. In dynamic analyses of space structures, three different types of damping matrices have usually been employed: system damping, free-free component damping and constrained component damping. This paper explains the reason for the discrepancies by considering a dynamic system composed of two substructures, each has two degrees-of-freedom. The close form expressions of the damping matrices are obtained on the same level of coordinates for direct comparisons, from which the reasons for the response discrepancies between different damping approaches in treating dynamic problems are interpreted.
