Abstract

Several well-known reduction methods for deformable multibody dynamics have been reviewed and compared. All of these methods have been borrowed from structural analysis. A recently proposed reduction method that is derived from the equations of motion, based on a mode condensation process, is also reviewed and compared against the other methods. The general conclusion of this investigation is that the standard condensation methods that are based only on fixed/non-moving boundary conditions should not be used in multibody dynamics. However, when the standard normal modes are accompanied by other properly selected modes, accurate results can be achieved. Similar results can also be obtained by the mode condensation method. The paper pays specific attention to two methods known as the Craig-Bampton reduction and the mode condensation.
