Extract the Rigid Body Properties of a Structure from Measured FRFs
The FEMtools Rigid Body Properties Extractor (Ft-RBPE) is a FEMtools add-on tool for extracting the rigid body properties of a structure from a set of measured Frequency Response Functions (FRFs). The following properties are obtained from the low-frequency portion of measured accelerances:
- Mass (M)
- Center of gravity locations (CoG)
- Mass moments of inertia (MoI)
- The rigid body properties can be used to validate a finite element model, for substructuring or motion analysis.
The Ft-RBPE is installed and used as an add-on to the FEMtools Framework or any other FEMtools configuration.
