Three measures of modal dynamic importance are studied for the purpose of ranking Craig-
Bampton substructure fixed interface mode shapes based upon their contribution to forces at …

This paper summarizes a study conducted to evaluate the fidelity of structural dynamic
models for the space station photovoltaic arrays and determine the effect of model fidelity on …

This paper describes the results of the modal test planning and the pre-test analysis for the X-
33 vehicle. The pre-test analysis included the selection of the target modes, selection of the …

In this article we discuss some of the aspects of coupling computer methods in control
system analysis with those in structural dynamics. This analysis is often called control …

Structural dynamic models of complex spacecraft are often assembled from a number of
component models. In this paper we present three methods for reducing the order of these …

A decentralized procedure is presented for the design of controllers for flexible structures.
Spatially significant components are created which approximate the response of a specific …

A decentralized suboptimal linear quadratic control design procedure which combines
substructural synthesis, model reduction, decentralized control design, subcontroller …

One of the most important tasks in pretest analysis and modal survey planning is the
selection of target modes. The target modes are those mode shapes that are determined to …

An algorithm for frequency response analysis of complex structures over large frequency
intervals is presented. The algorithm uses Adaptive Multi-Level Substructuring (AMLS) …

When examining control/structure interaction problems, a standard method for representing
the structure is to choose a truncated set of normal modes calculated from either a finite …
