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.

NVH Testing

NOISE, VIBRATION, AND HARSHNESS

Automotive manufacturers depend on noise, vibration, and harshness (NVH) testing to optimize vehicle performance and maintain a standard of comfort across their vehicle catalog.

FFT analysis software logo VR

FFT Analysis

Diagnose imbalances and analyze vibration from the engine or other components. FFT helps to determine which frequencies are excited and the amplitude at each frequency.

Order analysis software logo VR

Order Tracking and Analysis

Understand the vibration source at different frequencies and its relation to the reference RPM.

Modal testing software logo VR

Modal Testing

Identify a component’s response to an input. In ObserVIEW, acquire responses from each degree of freedom (DOF), and the software will calculate the average response for each DOF and generate a smooth transfer function for further analysis.

Octave Analysis

Analyze the frequency content of an acoustic signal and control the noise of the device under test.

Replicate Field Data

VibrationVIEW offers several test development methods to replicate the original environment of a product using recorded data. The result is a test profile that closely reflects—or is the equivalent to—the field environment.

Fatigue Damage Spectrum FDS software logo VR

FATIGUE DAMAGE SPECTRUM

Use recorded data to create an accelerated random test that represents a lifetime of fatigue damage.

Field Data Replication (FDR) software icon VR

FIELD DATA REPLICATION

Reproduce recorded field acceleration measurements on a shaker. The software performs an iterative time-history playback to replicate waveforms.

Sine Tracking Analysis Generation (STAG) software icon VR

SINE TRACKING, ANALYSIS AND GENERATION (STAG)

Generate an accurate representation of an environment with dominant sinusoidal vibration and background random vibration, such as an engine environment.

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.

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.

BSR Testing

Buzz, Squeak & Rattle

VR9500 and VR10500 Vibration Controllers

Vibration Research offers control hardware and shakers customized for low-noise operation used in BSR testing, sound limit testing, sound recordings, and anechoic chambers. The VR9500 and VR10500 controllers have a low noise floor (<70nV/√Hz) with a 130dB dynamic range. The controllers are compatible with all shakers and do not require a special board in the controlling PC.

Additional Features

  • Control sine, random, or shock vibration to 50,000Hz
  • 26,000 lines of resolution
  • 24-bit analog inputs

Ford Motor Case Study

Ford Motor Company FDS Case Study CoverLab technicians at a Ford Motor Company testing facility faced a puzzling and potentially dangerous dilemma. Were the company’s laboratory tests simply over-testing or were they accurately predicting a real and potentially dangerous situation? The facility used Vibration Research’s Fatigue Damage Spectrum software to solve its product challenge.
