A Modal Model is a set of mode shapes that has been scaled to preserve the mass, stiffness & damping properties of a structure.
In ME'scope, Residue mode shapes are obtained by curve fitting a set of FRFs.
A Modal Model of Residue mode shapes is obtained by curve fitting a set of calibrated FRFs, or by re-scaling UMM mode shapes. (see Tools | Scaling | UMM to Residue Shapes in the Basic Modal Analysis commands chapter.)
A Modal Model of UMM mode shapes is obtained by re-scaled a set of Residue mode shapes , or by re-scaling Residue mode shapes
A Modal Model of UMM mode shapes is obtained by solving for the modes of an FEA model. (see FEA | Calculate FEA Modes in the FEA commands chapter)
A Modal Model is required as input by the following commands in ME'scope,
Modes | Synthesize FRFs in a Data Block or Tools | Synthesize FRFs in a Shape Table
Transform | MIMO | Outputs in a Data Block
Transform | MIMO | Inputs in a Data Block
Transform | MIMO | Sinusoidal ODS in a Data Block or Tools | Sinusoidal ODS in a Shape Table
