Similar to the Damage Detection Module, the modes of the structure can be presented in a historical view. The Modal Parameter History Module has been designed for this. It presents the modal parameters as a function of the Analysis Sessions. In addition, it can automatically track modes determined in a reference state. Even though they change slightly in subsequent Analysis Sessions, the Mode Tracking is capable of keeping track of them. The tracked modes are presented as modal indicators that are inter-connected. Pointing at the line with the mouse allows further information of the particular tracked mode.
The features are summarized below:
Historical presentation of natural frequencies and damping ratios.
Historical export of modal parameters to SVS and UFF file formats.
Automatic mode tracking based on the estimation of a set of reference modes obtained from a specified set of reference Analysis Sessions.
Historical presentation of the tracked modes (Drawn interconnected). Natural frequencies and damping ratios – absolute and relative to their reference mode. Modal Assurance Criterion of the mode shapes relative to the mode shape of their reference mode.
Historical export of tracked modes to SVS and UFF file formats.
