Abstract

Calculation of the eigensolutions and eigensensitivities directly from the global structure is very time-consuming for a large-scale structure. In Chaps. 2 – 4, the FRFS and SRFS substructuring methods are introduced to improve computational efficiency. Nevertheless, discarding the higher-order substructural modes by these methods inevitably introduces trivial errors. This chapter introduces the IBSS method (Weng et al., J. Sound Vib. 330:3368–3380, 2011) to achieve higher accuracy of eigensolutions and eigensensitivities.
