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.
SINE RESONANCE TRACK & DWELL (SRTD)
Automatically detect transmissibility peaks from a sine sweep, and then dwell tests (time or cycles) run at those resonances.
RANDOM
Run Controlled spectrum random tests (tests with a spectrally shaped gaussian amplitude distribution).
INSTANT DEGREES OF FREEDOM (iDOF)
Run Controlled spectrum random tests (tests with a spectrally shaped gaussian amplitude distribution).
SINE-ON-RANDOM (SoR)
Run mixed-mode tests with sine tones superimposed on a random background.

Instant Degrees of Freedom
Something is awry with a PSD estimate that achieves total in-tolerance immediately after the test begins or immediately after a change in level, and this can hide dangerous over or under test conditions within specific frequency bands, and should be voided. The proper method of dealing with level changes, as well as a PSD estimation method that accurately and quickly estimates the true signal PSD significantly faster than the traditional averaging method: Instant Degrees of Freedom® (iDOF).
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.
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.
User Defined Transient Waveform Control
UDT allows for the creation of arbitrary periodic waveforms. UDT can better control short duration time history files, transient events, or very short road load data.
