Comparison between Dynamic Condensation Techniques in Automotive Application 2006-01-1093

A comparison between two well-known dynamic condensation techniques, the Craig-Bampton reduction technique and the Serep methodology, is discussed in the present paper. These techniques are usually applied in order to characterize the dynamic behavior of automotive subsystems. An automotive exhaust pipeline is taken into account and, through a modal-geometrical selection criterion of master degrees of freedom, the dynamic reduction techniques are analytically tested and experimentally validated. Finally, their performances and limitations are pointed out.
