Seismic Vibration Testing

Simulate the conditions of an earthquake to determine a structure’s response to a transient event and prevent damage and injury in the event of an actual earthquake. Shock response spectrum (SRS), transient waveform control, and other vibration control software to fulfill seismic vibration testing standards.

Shock Response Spectrum

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

  • Enter over 200 individual breakpoints
  •  Generate tests from a synthetic waveform or field recording
  • Manually adjust the parameters of the underlying wavelets or allow VibrationVIEW to automatically create and run a test without intervention

Additional Shock Software

User-Defined Transient

User Defined Transient Software IconUse a synthetic pulse or user-defined time-history waveform as the starting point, and VibrationVIEW will modify the wavelets to adjust the time-history waveform and meet the SRS demand. UDT offers better control of short-duration time-history files, transient events, or short road load data.

  • Minor adjustments made to the original time history
  • Meet or exceed RRS
  • Control on SRS vs. UDT
  • Adjusts wavelets to meet the required response spectrum


Earthquake test reporting softwareGenerate reports specific to IEEE 344 earthquake testing, including coherence plots, correlation plots, waterfall plots, and peak stress cycle counting.

High Channel Count Systems

Advanced Hardware System

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

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

Shaker Compatibility

VR’s controllers and control software are compatible with all shakers. 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 larger shakers? VR can help!


Chatter Monitor

The chatter monitoring package is capable of detecting and measuring chatter events. It is a beneficial feature if you are involved in seismic vibration testing of a product with relays or motor contactors, concerned about possible discontinuities in your relays, or need to evaluate the acceptance criteria for your relays (IEEE 501; ANSI C37.98).


Centrifuge Modelling

Researchers at the University of Colorado Boulder introduced a new servo-hydraulic shaker system for its 400 g-ton centrifuge and incorporated Vibration Research’s control software to optimize the drive signal. Learn more.

Test Standards

Bellcore (Telcordia) GR-63-Core Application

The Bellcore GR-63-CORE standard (formerly Telcordia) defines the spatial and environmental criteria for equipment in these regions. The VibrationVIEW software can run earthquake tests that meet the Bellcore standard and any other earthquake time-history waveform.

IEEE-344 Earthquake Control

IEEE STD-344 defines the procedures that demonstrate that Class 1E equipment can perform during a seismic event. The equipment’s functionality must ensure that the reactor is in a safe condition after shutdown and prevent or minimize the possibility of public radiation exposure.

The VibrationVIEW software can perform several IEEE 344 procedures, including:

  • Input filtering for measurement of zero period acceleration (Annex A)
  • Multiple damping plots (Annex A)
  • Time interval waterfall PSDs (Annex B)
  • Sine beat/dwell/sweep fragility testing (Annex C)
  • Peak stress cycle counting (Annex D)
  • Coherence plots (Annex E)
  • Correlation plots (Annex E)

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.

Multi-Axis Testing

The VR9500/VR10500 can be used to control multi-shaker systems such as electrodynamic, servo-electric, and servo-hydraulic systems. Available multi-shaker control options including dual-axis with phase control, 3-axis (x-y-z) control, multi-loop (4-post) control, and earthquake controls.


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.
