CALCULATION OF COMPONENT MADE SYNTHESIS MATRICES FROM MEASURED FREQUENCY-RESPONSE FUNCTIONS, PART-2 - APPLICATION

This paper demonstrates how to calculate Craig-Bampton component mode synthesis matrices from measured frequency response functions. The pro cedure is based on a modified residual flexibility method, from which the Craig-Bampton CMS matrices are recovered, as presented in the comp anion paper, Part I (Morgan et al., 1998). A system of two coupled bea ms is analyzed using the experimentally-based method. The individual b eams' CMS matrices are calculated from measured frequency response fun ctions. Then, the two beams are analytically coupled together using th e test-derived matrices. Good agreement is obtained between the couple d system and the measured results.
