Aerospace Vibration Testing

Aerospace vibration testing requires adequate test severities and consistent, repeatable results. Vibration Research offers many aerospace testing solutions, including short-duration random tests, high-channel-count control, shock response spectrum, and more.

Random Vibration Testing

Validate Reliability

In VibrationVIEW, fulfill test standards with random software features such as:

  • Frequency/amplitude breakpoint table (up to 9,999 entries)
  • Individual channel tolerances (PSD and RMS)
  • Control and channel aborts (RMS)
  • Spectral limiting/notching
  • Multi-channel average and extremal control
  • 50 to 26,000 lines of control (or up to 50,000Hz with the VR9203 High-Frequency option)
  • Probability density function (PDF) display

Random Software

Kurtosis Control – Kurtosion

Present-day methods of random testing assume a Gaussian mode of distribution where the kurtosis value equals three. However, not all data fit Gaussian distribution, and this assumption can result in under-testing.
A better method is to adjust the distribution of data to reflect the field environment, which involves the adjustment of kurtosis.

Kurtosion is a closed-loop method of kurtosis control developed by Vibration Research. It allows for the adjustment of kurtosis levels while maintaining the test profile and spectrum attributes.

Short Duration Testing – iDOF

Instant Degrees of Freedom (iDOF) employs an advanced algorithm to deliver accurate and low-variance PSD estimates that are calculated quicker than traditional averaging. With iDOF, a test engineer can verify that the control PSD is within tolerance and determine how the test affects the DUT. Most importantly, the engineer can stop the test before the energy from a vibration resonance inflicts damage.

Force Limiting

Prevent Over-Testing

  • Apply a force limit to one or multiple axes during a sine sweep.
  • Sum the output of the force transducers and notch on the total force applied during a Random test.
