Test Modules
SINE – Run swept and/or fixed-frequency sine wave vibration tests, with control of acceleration, velocity, and displacement.
SINE ON SINE – Run mixed-mode tests with up to 32 sine tones simultaneously.
RANDOM – Run Controlled spectrum random tests (tests with a spectrally shaped gaussian amplitude distribution).
iDOF® – Prevent under or over testing on high value products where tight tolerances and short duration random testing is required.
SINE ON RANDOM – Run mixed-mode tests with sine tones superimposed on a random background.
RANDOM ON RANDOM – Run controlled spectrum random tests with swept random “tones” superimposed on a random background.
KURTOSION® – Re-introduce the high acceleration peaks back into your random vibration tests. Our patented -solution to when your in-service vibration environment is not Gaussian.
RANDOM IMPORT – Import your time-based vibration data recording and convert to a power spectral density curve with breakpoint table.
FATIGUE DAMAGE SPECTRUM – Measure your products fatigue and calculate its lifespan. Commonly used life acceleration techniques are applied to shorten test time.
SHOCK – Run standard classical shock pulses as well as (optional) user-defined or SRS synthesized transient pulses.
SRS – Perform Shock Response Spectrum (SRS) analysis. Run a shock pulse defined by a frequency vs. G peak table. Many different waveform synthesis generation techniques included.
TRANSIENT CAPTURE – Capture a transient waveform for post process. Use alone for data acquisition, or with SRS for Shock Response Spectrum analysis.
FIELD DATA REPLICATION – Reproduce, in your test lab on your shaker, the actual acceleration waveforms you measure in the field. The controller automatically compensates for shaker and fixture response.
EARTHQUAKE – Run a shock pulse defined by a frequency vs. G peak table. Many different waveform synthesis generation techniques included.
HALT/HASS VIBRATION TABLE VALIDATION:
WHAT IS THE TRUE MAGNITUDE OF FORCE THE DEVICE UNDER TEST EXPERIENCES
- Determine how the energy is distributed across the table compared to the control accelerometer located at the center bottom of the table
- Validate the Power Spectral Density in each Quadrant of the Table
- Validate the proper location to place the Device Under Test
- Validate the proper fixture configuration for correct energy transfer to the Device Under Test
- Validate detailed vibration data of subcomponents throughout the Device Under Test
- Identify unexpected movement of electronic components from resonance frequencies
- Compare the Calibration data with Validation Data
- We use ISO 17025 Calibrated Vibration Research VR 9500 controllers – 16 channels
- We use ISO 17025 Calibrated Single Axis and Triaxial Accelerometers to capture data
