Random Vibration Control

Random control is one of the two basic and most common excitation modes for Environmental Shaker testing. Random performs real-time closed-loop control of PSD profiles. The m+p VibControl vibration control system allows the user to designate all input channels as control, watchdog and/or measurement channels.

  • Key Features
  • Applications

Random Vibration Control

  • Fully compliant with DIN, MIL-STD 810 and many other standards
  • Support on electrodynamic and hydraulic shakers
  • Frequency range up to 12.8 kHz or 40 kHz, hardware dependent
  • All input channels available as control, watchdog and/or measurement channels
  • Control strategy: average, maximum, minimum
  • Notching/force limiting
  • True multi-tasking without loss of real-time control
  • Resolution up to 25,600 lines, selectable in 8 steps
  • Kurtosis control accelerates structural life testing; control of the excitation by adjustment of the probability density function (PDF)
  • Time data display and frequency display
  • Seamless import/export of test results into applications such as MS Word, MS Excel,
    and m+p Analyzer for dynamic signal analysis
  • Measuring and monitoring DC signals for functional testing

Random Data Reduction

  • Online analysis of measured data or taped random data (PSD averaging)
  • Measured data can be recorded on throughput disc
  • Scalable hardware from 4 to 1,280 channels
  • Fully replaces tape recorder

  • Random testing is commonly used in aerospace and military applications for duplicating such events as aircraft take-off, rocket launch, or transportation over rough terrain.
