Vibration testing will aid in your understanding of how your component designs will perform when vibratory stresses are present. Determining where, when and how a component/product may respond to vibratory conditions provides you with the advantage of determining the effectiveness of a given design. DATASYST can support your success by adding random, sinusoidal and combined environmental vibration testing to your test program.
DATASYST provides the following vibration testing methods:
Random Vibration Testing - replicates complex frequencies in a chosen bandwidth. Vibration environments may have input from multiple sources, such as wheels over a road. In these vibration exposures, it may be more accurate to analyze and test using random vibration.
In random vibration the primary concern is the spectral content of the vibration being generated. Most random vibration tests are conducted using Gaussian random suppositions where maximum amplitude is not definable, and levels are measured in RMS values.
Sinusoidal Vibration Testing
With sinusoidal vibration, the relationship between acceleration, velocity and displacement is fixed and frequency dependent. Variation in any one of these three parameters affects another, and for this reason, all of them should be considered simultaneously when specifying or observing sine vibration.
Sine Sweep Vibration Testing - are sweeps across a frequency spectrum at a specific rate to identify resonant frequencies of a Unit Under Test (UUT).
Sine Dwell Vibration Testing - are dwells at a specific frequency, often at a resonant frequency, to duplicate a worst case condition for the UUT.
Sine-on-Random Vibration Testing - is performed by overlaying a sine dwell on a random vibration profile.
Combined Environment Vibration Testing - allows exposure of a UUT to vibration and environmental conditions (hot/cold) simultaneously.
