Applicable (NVH) Vibration Control Software
SINE
Enter two values out of the four between Acceleration, Frequency, Velocity, or Displacement, and the calculator will do the rest.
RANDOM
Measure your products fatigue and calculate its lifespan. Commonly used life acceleration techniques are applied to shorten test time.
KURTOSION®
Re-introduce the high acceleration peaks back into your random vibration tests.
FATIGUE DAMAGE SPECTRUM
Measure your products fatigue and calculate its lifespan. Commonly used life acceleration techniques are applied to shorten test time.
FIELD DATA REPLICATION
Reproduce, in your test lab on your shaker, the actual acceleration waveform you measure in the field.
Copy > Paste with Excel & Word in VibrationVIEW
Copy & Paste Vibration Test Profiles and Graphs into and out of Microsoft Word & Excel. This is especially useful when sharing profiles with colleagues or entering from a customer.

Ford Motor Case Study
Lab technicians at a Ford Motor Company testing facility were facing a serious dilemma they couldn’t seem to solve. A fuel-rail on their 5.0L and 6.2L BOSS engines experienced several lab testing failures on the dynamometer that had never been observed in the field. These failures naturally created some concern. Were the company’s laboratory tests simply over testing the fuel-rail or were they accurately predicting a future real life and potentially dangerous situation?
Electric Vehicle (EV) Battery Testing
IEC 62660-2 (2018)
This is a reliability and abuse test for auto traction lithium-ion batteries.
SAE J2464 (2009)
This is an abuse test, including hazardous substance monitoring, mechanical, thermal, and electrical abuse.
UN 38.3 (2016)
The purpose is different for this standard; it has a focus on the safe transportation of lithium metal and lithium ion batteries, including altitude, temperature, vibration, shock and impact/crush testing.
Buzz, Squeak, Rattle (BSR) Vibration Testing
Control software and shakers customized for low noise operation. This is typically used for Buzz, Squeak & Rattle testing, sound limit testing, sound recordings, and anechoic chambers.
Automobile Companies Using VR Products
Kurtosis Control vs Fatigue Damage Spectrum
Vibration test facilities want to accurately test products but do so in an efficient time period. Vibration Research Corporation has two techniques to help test engineers rapidly accelerate the random vibration tests. Those two methods are Kurtosis Control and Fatigue Damage Spectrum.
Crankshaft Resonance Track & Dwell (SRTD)
Auto-detect transmissibility peaks from a sweep. Peak Tracking is a better way to track a shifting resonance during the Dwell portion of a Sine Resonance Track and Dwell (SRTD) test, delivering superior results to the traditional Phase Tracking method. VibrationVIEW offers you both options.
Four Post Random Vibration Tests
RANDOM
Control 2, 3, or 4 output drive loops simultaneously
TRANSIENT/SHOCK
Control 2, 3, or 4 output drive loops simultaneously, output phase is synchronized
FIELD DATA REPLICATION (FDR)
Control 2, 3, or 4 output drive loops simultaneously, output phase is synchronized
SINE
One master controller is used with the drive signal T’d off for the other controllers. Use multiple input accelerometers for Sine averaging, max, min, or extremal control.
Compare Field Data to a Specification
Industry standard vibration tests are used by hundreds of labs to test thousands of products every year. But how closely do the standard tests duplicate the real-world operational environment of those products? Are you over or under testing your product? Is this the best representation of a real world environment?
Field Data Replication
Reproduce your data 1:1 as it happened in the real world (transportation simulation). However, this can be time consuming.
Random Import
Run your recorded data. Run Random peaks as average, peak hold or somewhere in the middle. But, for how long?
Fatigue Damage Spectrum
Real world data on the shaker in an accelerated way.
