The Grid Participation utility allows you to plot panel grid participation results and then use advanced scaling contour
capabilities in HyperView to isolate key contributing areas.
Generates and post-processes engine order related data from an OptiStruct or Nastran frequency response analysis that
contains either RPM-based loading subcases or order-based loading subcases.
PreTest allows prediction and optimization of the sensor locations (accelerometers) for measurements and directions along
with test excitation point location, a very important step in the experimental modal analysis process directly affecting
the accuracy of test results. Driving point residue (DPR) calculation gives information on optimum point for excitation
location.
Frequency Response Assurance Criterion (FRAC) is a measure of the correlation between two frequency response functions
(FRFs) representing the same input-output relationship.
The Mount Optimization utility helps to predict powertrain rigid body mode frequencies and kinetic energy distribution,
which play a critical role in optimizing the mount stiffness and layout configuration, by decoupling powertrain rigid
body modes and reducing vibration transmission.
To access the Model Correlation utility in HyperView, you must register the NVH preferences file and load
the NVH Utilities.
From the File Menu, click Load > Preference File.
The Preferences dialog is displayed.
Select NVH-Utilities from the Preferences dialog.
Click Load.
The NVH menu is added and displayed on the menu bar.
From the NVH menu, select Model Correlation.
An NVH-Utilities tab is added to the browser.
Note: This browser tab
contains the Load tab. It also contains icons for other utilities, such as
modal participation and order cut analysis. Select an icon to toggle between
the utilities.
To close the NVH-Utilities tab, click on the X in the
upper right corner of the dialog.
