33Hz resonance test vertical vibration table

33Hz resonance test vertical vibration tableProduct Introduction:

Sweep frequency vibration

definitionDuring the testing process, the frequency of the vibration table wasContinuously changing within a certain range according to a certain pattern(such as from low frequency to high frequency, and then back again), the amplitude may be constant or may vary according to a certain spectral line.

Core Features：

• frequency variationFor example, scan back and forth linearly or logarithmically between 5Hz and 500Hz.

• Evaluate the response within the frequency rangeQuickly reveal the dynamic characteristics of the product throughout the entire frequency range, especially the resonance frequency.

• time dimensionThe frequency changes over time, and the dwell time at each frequency point is very short.

Sweep frequency method：

• Linear sweep frequencyThe frequency increases linearly with time (such as increasing by 10Hz per second). In physical terms, the high-frequency testing time is relatively short.

• Logarithmic sweep frequencyThe frequency increases logarithmically (such as equal time per octave). This is a more commonly used method because it scans slowly in the low frequency range and quickly in the high frequency range, which is more in line with the characteristics of most physical systems and can ensure that each octave band can withstand the same number of vibration cycles.
