Random Testing

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

  • Tabular frequency/amplitude breakpoint table
    • Up to 9,999 entries
    • Enter values manually or copy/paste a table from Excel
  • 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
  • Probability density function (PDF) display

Short Duration Testing – iDOF

iDOF Banner

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 – Kurtosis Control


Kurtosion

A closed-loop method of kurtosis control developed by Vibration Research. It allows you to adjust the RMS and kurtosis levels of a random test while maintaining the test profile and spectrum attributes.

Full RMS control
Moves acceleration values from the mean towards peak levels with no change in the GRMS

Full dynamic range
Controls the kurtosis of the acceleration without any reduction in dynamic range

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.

Shaker Compatibility

VR’s controllers and control software are compatible with any shaker. Our qualified sales team can work with you to select the right equipment at the right price. We’ll put together a custom package of hardware, software, and shakers for all your foreseeable testing needs.

Does your lab require large shakers? VR CAN HELP!

Shakers

ObserVR1000 & VR Mobile

The ObserVR1000 hardware can be controlled remotely with the VR Mobile application, which runs on a smartphone or tablet using a WiFi connection. Set up, monitor, and modify field data recording without a wired configuration.

Autonomous DAQ

MONITOR TESTS REMOTELY
Observe live data recording from any mobile device. Select, start, and stop the test; analyze issues with a live FFT display.

SET UP AUTONOMOUS ACQUISITION
Define any number of triggering events to record data without interference. Save processing time, capture transient events, drive external equipment, and more.

CONNECT A TACHOMETER
Configure a dual or quadrature tachometer to measure rotation. Encoder types include wheel, rotational, or scalar.

DISPLAY GPS DATA
View position updates at about 1Hz along with GPS timebase synchronization. Then, play the GPS media files in sync with a waveform recording.

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.
