NVH Improvements

Adam Remmel

The noise, vibration, and harshness (NVH) capabilities of Mechanical have been improved to include multiple RPMs. It is now possible to connect a Harmonic Acoustics analysis to a Harmonic Response analysis with multiple RPMs. The velocity data of each RPM can then be transferred for all frequencies. Sound pressure level microphone and waterfall diagram results can be viewed. Under the Import Load group of Harmonic Acoustics, a new option is available to create Imported Velocity objects for all RPMs defined in the Harmonic Response and synchronize the Analysis Settings. After the analysis is complete, it is now possible to export a WAV file of the results.
