SimAcademy Webinar Archive: FRF, FBA and TPA Capability in MSC Nastran 2010
The frequency response function (FRF) and FRF-based assembly (FBA) are new capabilities in MSC Nastran. FRFs can be used to represent components. This capability facilitates the computation of the FRFs of individual components and also the subsequent computation of the FRFs of an assembly of such components from their individual FRFs. It supports test FRF components in the FBA process. Also it allows the FBA process to handle a single FRF component without any connection data. Such an FRF-based assembly process represents an alternative to component mode synthesis (or Modal Substructuring). This method also lends itself to tracking load paths or energy flows through a structure. This approach may be regarded as an alternative to mode participation studies. This latter feature, commonly referred as transfer path analysis (TPA). Note that this session is NOT a substitute for formal training.
