Vibration Control Systems
Compatible with All Shaker Types
Set up and safely control vibration and shock shaker tests with reliable hardware and user-friendly software. Test types include sine, random, sine-on-random, random-on-random, classical shock, SRS, and more.
Vibration Controllers | Stackable units with a range of 8 to 512 channels (mix & match units between shakers).
Innovative Software | Set up and monitor vibration and shock tests with automated & customized reports.
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 equivalent to—the field environment.
FATIGUE DAMAGE SPECTRUM
Use recorded data to create an accelerated random test that represents a lifetime of fatigue damage.
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 AND GENERATION (STAG)
Generate an accurate representation of an environment with dominant sinusoidal vibration and background random vibration, such as an engine environment.
Define & Run Shock Tests
Perform shock tests on a shaker with classical pulse types or develop more complex profiles with the shock response spectrum (SRS). User-defined transients help meet seismic standards.
Classical Shock
Perform closed-loop control of transient waveforms and access the most used classical shock pulses in the industry.
User-Defined Transient
Create arbitrary periodic waveforms and have better control over short-duration time history files, transient events, and short-load data.
Shock Response Spectrum
Evaluate a device’s response to a transient event likely to occur in the end environment; define SRS parameters and synthesize a pulse to meet a specified SRS curve.
Modal Testing
Perform experimental modal analysis to identify the natural vibration frequencies of a structure and its response to excitation. ObserVIEW calculates an average response for each hit location and generates a smooth transfer function (FRF).
- Perform roving hammer or roving accel modal testing
- Manage table of hits per location and review hits
- Average multiple data recordings
- Calculate decay rate from transient ring-down events
- Manage the acquisition channel using a large, interactive display
Sine Reduction
Synchronize a vibration control system with a VR I/O unit to increase channel count and/or validate the frequency response with a separate controller. Accurate frequency tracking ensures the identification of resonant frequencies for product development and qualification.
- Use the COLA output of any controller to configure shaker control with a VR I/O unit
- Define tracking filters for sine sweep
- Report results for independent verification of the structure’s response
- Configure abort limits for all channels or individual ones
