Vibration Testing

That device on which you need to perform vibration testing will spend its lifetime in different environments. Because these environments exhibit unique vibration profiles, we use vibration control techniques tailored to each environment.

Our vibration controllers can control with sine, random, sine-on-random or narrow band random-on random control strategies.

Since vibration testing has been used for the longest time because generator-based sine wave output controllers were the simplest to build. Unfortunately, sine vibration has few real-world parallels. But sine vibration is still useful for experimentation and for determining resonances.

A more accurate simulation of many real-world conditions is achieved with random vibration control. Random vibration testing subjects the product to all of the frequencies within a band of frequencies. A typical random vibration control strategy will shape the vibration energy profile (power spectral density – PSD) to correspond with frequency distribution of the in-use environment.

Sine-on-random vibration testing superimposes a sine vibration signal onto a random signal to simulate helicopter or aircraft gunfire environments. Multiple sine frequencies can be superimposed at one time and the sine tones can be swept throughout the spectrum.

Narrow band random-on-random vibration testing superimposes a sweeping narrow band random vibration signal onto a random vibration signal to simulate the track patter of tracked vehicles.

Clients with HALT reliability testing requirements can combine a rapid temperature ramping environment along with vibration testing in an AGREE chamber using temperature transition rates as high as 20°C per minute.

Where clients do not have their own vibration fixtures, we can design, fabricate and qualify a vibration fixture using our in-house vibration fixture team. Many times this internal capability has saved our clients time and cost by not having to source separate suppliers for testing, design, fabrication and fixture qualification.

In addition to the vibration fixtures, we also designed and fabricated a custom head expander as well the supplementary support system and integrated both with the shakers existing package support system.
