Abstract

This study explores the Frequency-Based Substructuring (FBS) analysis of a Bolted Flanged Pipe Assembly (BFPA) to investigate its dynamic behaviour. The motivation for employing the FBS method lies in its potential to integrate different sources of results of substructures for dynamic behaviour evaluation. In this study, the FBS method is utilized to couple the finite element (FE) model of a Flanged Pipe (FP) substructure with the FE model of Bent Elbow Pipe (BEP) substructure for investigating the coupled FRF of the assembled system, which is the BFPA. Bolted joints within the BFJA are represented with rigid elements. The FBS method is used to compute the coupled Frequency Response Functions (FRFs) of the BFPA. The coupled FRF is compared with the FRF obtained from experimental modal analysis (EMA). This comparison evaluates the accuracy of the method and shows possible way to improvement it. The importance of this study may be seen in many applications such as aerospace, automotive and civil engineering.
