WebbNAVMAT P-9492 Random Vibration Profile – The NAVMAT profile is a random vibration profile with a starting frequency of 20Hz and a vibration magnitude of 0.01 G2/Hz. The vibration magnitude increases at the rate of 3dB/Octave to 80Hz where the vibration magnitude is 0.04 G2/Hz. The vibration magnitude is maintained until the frequency … Webb9 sep. 2024 · Sinusoidal vibration tests typically are not as helpful as random testing in certain condition since a sine test focuses on single frequency consistently. A random vibration test, however, always excites all the frequencies within a defined spectrum.
