Question: Where can I learn more about Frequency Response Functions, FRF Based Assembly, and Transfer Path Analysis in MSC Nastran?
Answer: You can watch this SimAcademy webinar FRF, FBA and TPA Capability in MSC Nastran.
Here is a preview of the SimAcademy Webinar.
Details of the webinar
The frequency response function (FRF) and FRF-based assembly (FBA) capabilities were originally introduced to MSC Nastran in 2007. 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.
During this session, we will cover:
- Technique used in MSC Nastran
- FRF/FBA Capability in MSC Nastran
- FRF Concept
- FBA Concept
- TPA Concept
- Distinction Between External Superelement (EXTSEOUT) Based Approach and FRF Based Approach for Frequency Response Analysis
- Advantages of FRF Based Approach
- FRF/FBA Usage Procedure
- Case Control and Bulk Data for FRF/FBA Usage
- Illustrative Examples
