Military Standards

US Department of Defense Test Method StandardMilitary 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

VibrationVIEW Sine on Sine Test SettingsMilitary 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.

Short Duration Random Testing

Instant degrees of freedom iDOF softwareInstant Degrees of Freedom (iDOF) employs an advanced, patented 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.

Shock Vibration Testing

CLASSICAL SHOCK

Perform closed-loop control of transient waveforms and access the most used classical shock pulses in the industry.

USER-DEFINED TRANSIENT WAVEFORM CONTROL

Create arbitrary periodic waveforms and have better control over short-duration time history files, transient events, and short load data.

SHOCK RESPONSE SPECTRUM (SRS)

Evaluate a device’s response to a transient event likely to occur in the end environment. In VibrationVIEW, define the SRS parameters and synthesize a pulse to meet a specified SRS curve.

It is often acceptable to replicate far-field characteristics of a pyrotechnic shock with mechanical excitation. Test engineers run a shock response spectrum (SRS) test on an electrodynamic shaker to do so. VR’s vibration control systems are compatible with any electrodynamic shaker.

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. It is an advanced hardware system for complex applications.

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

Mix & Match Controllers with Shakers

Product stack with ObserVR1000, VR9500 and VR10500

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.

One 12-channel Control System or 3 separate 4-channel Control Systems

Dual 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, and Shock test modes.
