Military Standards

US Department of Defense Test Method Standard

Military and defense equipment must be able to withstand some of the harshest environments. MIL-STD Version H emphasizes a tailored approach for environmental testing and is focused on ensuring that systems withstand the extreme climatic, shock, and vibration environments expected during a service lifetime.

Vibration Research’s testing systems address acceleration, shock and transport shock, gunfire vibration, and random vibration. We’ve spent a significant amount of time with MIL-STD-810H and put the new test profiles into the current version of the VibrationVIEW software.

Mixed-Mode Vibration Testing

Military and defense applications typically use sine-on-random (SoR) and sine-on-sine mixed-mode vibration. Mixed-mode testing simulates complex field environments that are not purely random or sinusoidal but rather a combination of vibration modes.

A helicopter gunfire test is a common application of SoR testing. Helicopters are subject to common random vibration, but gunfire from the helicopter introduces high-G sinusoidal vibration. As an SoR test better represents real-world conditions, it is the preferred test procedure for this application.

Random Software Innovations

Instant degrees of freedom iDOF softwareInstant Degrees of Freedom (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, you can verify that the control PSD is within tolerance, determine how the test affects the DUT, and stop the test before the energy from a vibration resonance inflicts damage.

Kurtosion®

Kurtosion allows you to adjust the RMS and kurtosis levels of a random test while maintaining the test profile and spectrum attributes.

Clip What Matters

TruClip predicts the drive signal and removes peaks that would exceed the acceleration, velocity, or displacement limitations of the shaker.

Mix & Match Controllers with Shakers

Control modules can be used independently on separate shakers or linked into a single stack for jobs requiring a higher channel count (up to 512 channels total).

This cost-effective solution creates substantial savings for our customers.

High Channel Count Systems

VR10500 Vibration Controller

The VR10500 is a high-powered option for advanced vibration testing. VR engineered the VR10500 to coordinate with high-channel-count and multi-shaker systems.

Features

  • 16 channel count system (8 channel min.)
  • Up to 512 input channels
  • Multiple shaker systems
  • Controller and analyzer combination
  • Advanced controller configurations
  • Up to 6 outputs (4 analog/2 digital)

Multi-axis with Phase Control

Test oversized products by synchronizing two shakers with the same test profile. The VR9500 and VR10500 vibration controllers can perform dual-loop control in the Sine, Random, Shock, and FDR test modes.

Copy > Paste in Excel & Word

Copy and paste vibration test profiles and graphs between VibrationVIEW and Microsoft Word/Excel. This feature is especially useful when sharing profiles with colleagues, entering data from a customer, or entering lengthy or complicated test profiles.
