Without more details, I can only guess the first peak is the first harmonic, second peak is the second harmonic and so on.. Look into these resources to understand more about fft 1. http://www.feadomain.com/download.php?view.27 2. http://www.feadomain.com/download.php?view.26 3...

There are some guides available from HKS and MSC. Check here http://www.feadomain.com/download.php?list.25

It is difficult to come up with an absolute percentage. The corrrelation depends on the geometery, material properties and boundary conditions. Also, there is always some variability due to test setup. Considering all this, less than 20% variation for linear static analysis and 10% variation for...
