Decoupled space station/shuttle analysis in the presence of non-classical damping and geometric non-linearities

[摘要] Dynamic analysis methods for computationally demanding systems are examined. Component Mode Synthesis methods are detailed and their limitations established. Decoupled analysis is offered as a solution for problems that traditional methods are incapable of addressing, such as systems with non-classical damping or geometric non-linearities. The methodology of decoupled analysis is detailed along with three modifications to the basic decoupled analysis method. This method is then applied to two large problems involving the International Space Station and the Space Shuttle.
