19.12. Noise, Vibration, and Harshness

NVH is an add-on to the Ansys Mechanical User Interface that enables you to preprocess/postprocess Noise, Vibration, and Harshness (NVH) results:

  • It streamlines Modal Assurance Criterion (MAC) calculations through FEA-Experimental model comparison.

  • It is able to reconstruct elastic stress/strain fields from modal superposition/harmonic analyses or tests.

  • It allows computation of the Frequency Response Function (FRF) in terms of Compliance, Mobility or Accelerance.

  • It offers a pre-test environment that allows identification of optimum sensor and exciter locations for vibration tests.

  • It offers an XML Converter Wizard to convert electromagnetics load data from .csv format (created by an external analysis, such as Maxwell) to .xml format (compatible with the Imported Remote Loads object in Mechanical).


Note:  The NVH Add-on is only available on the Windows operating system.


For more information about this add-on, see NVH Toolkit Add-on in the Mechanical Add-ons Guide.
