Recorded Data to Improve SRS

Test engineers use synthetic waveforms to create an SRS pulse for seismic vibration testing. Often, there is no synthetic waveform that matches a real-world transient event. Therefore, engineers need a more realistic way to create an SRS test.

A modified user waveform created from an enveloped set of recordings maintains real-world characteristics. Use this method to create a complex shock test that reflects a recorded event.

SRS Software

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 curve.

SRS Software

EASY TEST ENTRY
Enter up to 200 frequency/amplitude breakpoints of the background random acceleration spectrum in an easy-to-read tabular form.

TEST GENERATION TECHNIQUES
Test generation techniques including linear and exponential chirp, WavSyn, burst random, linear and exponential chirp on burst random, enveloped random, and burst sine. Alternatively, iterate from a user waveform.

MANUAL WAVELET MANIPULATION
Manually adjust the parameters of the underlying wavelets or allow VibrationVIEW to automatically create and run a test without intervention.

DATA PLOTS
SRS pseudo velocity and SRS acceleration plots; acceleration for primary (+), primary (-), or maxi-maxi.

High Channel Count Systems

VR10500 Vibration Controller

Advanced Hardware System

The VR10500 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 and 2 digital)
  • Controller and analyzer combination
  • Advanced controller configurations

Shaker Compatibility

VR’s controllers and control software are compatible with all shakers.

Does your lab require larger shakers? VR can help!

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.

Shakers

Large electrodynamic and servo hydrolic shakers

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).

Additional Software

Create arbitrary periodic waveforms with the Transient Waveforms Control software module. User-defined transients offer better control of short-duration time history files, transient events, or short road load data.

User Defined Transient Software Icon

User-Defined Transient/SRS Control Modification

Use 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.

  • 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

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.

Verizon Seismic Testing with VibrationVIEW

Seismic Test | Best for a good reason by Verizon Careers on Thursday, August 9, 2018

We test our switches, routers, and transport gear against #earthquake simulations up to 8.3 on the Richter scale. As Engineer Janette Bouché explains, we don’t know when the next one is coming, but staying connected will be vital when it does. #emergencyplanning #vzcareers
