Get a demo of frequency response analysis results interpretation.
- [Instructor] In this video, we're going to look at…some aspects of interpreting frequency response analysis.…Now, if we look at the infrequence to response output…in Autodesk Nastran In-CAD,…we can have magnitude and phase.…It's available within contour plots…and also in XY plots or graphs.…We can also have real and imaginary.…That's also available both in contour plots and graphs.…The latter though is not used very much in engineering.…Both magnitude and phase plots…are really needed to describe what's happening.…
If we look at the plate displacement response,…the three edge positions indicated,…this is the magnitude response.…Then, we also get phasing.…So, at the first three natural frequencies,…what's happening as we pass through those on the phase plot,…there's a change in phase.…So, F1 is the first natural frequency,…there's a change in phase running through that.…So, the natural frequency actually represents…like a changing state as for other phases are concerned.…And we see that repeated…for mode two, or frequency two, and frequency three.…
