Applicable Defense Vibration Control Software
SINE
Enter two values out of the four between Acceleration, Frequency, Velocity, or Displacement, and the calculator will do the rest.
RANDOM
Run Controlled spectrum random tests (tests with a spectrally shaped gaussian amplitude distribution).
SINE-ON-RANDOM
Run mixed-mode tests with sine tones superimposed on a random background.
RANDOM-ON-RANDOM
Run controlled spectrum random tests with swept random “tones” superimposed on a random background.
SHOCK
Run standard classical shock pulses as well as (optional) user-defined or SRS synthesized transient pulses.
SHOCK RESPONSE SPECTRUM (SRS)
Perform Shock Response Spectrum (SRS) analysis. Run a shock pulse defined by a frequency vs. G peak table.
Copy > Paste with Excel & Word in VibrationVIEW
Copy & Paste Vibration Test Profiles and Graphs into and out of Microsoft Word & Excel. This is especially useful when sharing profiles with colleagues or entering from a customer or even those lengthy and difficult test profiles.

Shock & Vibration MIL-STD Testing
Military and Defense equipment must be able to withstand some of the harshest environments on earth. Vibration Research solutions address acceleration, shock and transport shock, gunfire vibration and random vibration. Version ‘H’ emphasizes a tailored approach for environmental testing, focused on ensuring that systems will be able to withstand the harsh climatic, shock and vibration environments expected during a service lifetime.
We’ve already spent significant time with MIL-STD-810H, working to put the new test profiles into the current version of VibrationVIEW software. MIL-STD-810G was previously installed a number of versions ago.
Mixed-Mode Vibration Testing
Mixed-Mode vibration testing typically involves Sine-on-Random and Sine-on-Sine for Military and Defense purposes. Here is a typical gunfire Sine Vibration:
- Sweep from 0.95 to 1.05 of the harmonic center frequency at a sweep rate of 0.5 octave/min (7.5 min per frequency)
- For harmonic frequencies 66, 132, 198, 263 Hz
- 5G maximum acceleration
- Test capability permitting- to minimize test time and enhance gunfire vibration simulation, conduct 2 or more sine dwells (“smokestacks”) concurrently in a phase-uncorrelated manner
Using Data to Improve SRS Development
Shock Response Spectra (SRS) testing uses a synthesized pulse to drive a shaker, simulating a transient event. Originally developed to replicate Seismic shocks, the SRS approach is also widely used for defense and aerospace applications.
Dual Axis with Phase Control
Test oversized products using Dual Axis with Phase.
Dual Loop control is achieved by using the two outputs from one VR9500 Revolution controller hardware unit. The drive output and the aux (COLA) output are both used to drive different shakers. The same profile drives both shakers.
Vibration Control Compatibility
VR’s vibration controller and vibration control software are comparable with any electrodynamic or servohydraulic shaker. Even better, our controller comes with a lifetime hardware warranty when your maintenance is current. Try one out for free with ALL software enabled today!

Short Duration Random Launch Application
Too often, vibration tests are run to “force fit” a smooth line by running them at a low level (below demand) and taking that averaged PSD and simply multiplying it by a factor to bring it to full level. This method is invalid as it’s based on the false assumption that the behaviors of a product at a high level would exactly mimic that of it at a low level. This vibration testing protocol is unfortunately very common and is exactly why high value products are over and under tested.
Harness the exactness, efficiencies and peace-of-mind that iDOF now offers to vibration control practitioners.
