WebAug 1, 2008 · The lowest vibration frequencies of a cantilever clamped at one end are in the ratio 1 : 6.27 : 17.55. That matches your frequencies of 49, 307, and 861 Khz very closely. In your frequency analysis, the resonance at 0 Hz suggests you didn't apply any constraints, so the frequencies will be different (and larger). WebThe frequency-domain modal analysis is then applied with fine frequency stepping to define the multiple resonances. In contrast, the AWE method is best used for analysis of smooth frequency responses containing a single resonance or no resonance.
