Sine Vibration Control

Sine control is one of the two basic and most common excitation modes for Environmental Shaker testing.
This control mode performs real-time closed-loop control of swept sine vibration.

Key Features

  • Fully compliant with DIN and MIL-STD 810 standards
  • Support on electrodynamic and hydraulic shakers
  • Frequency range up to 20 kHz
  • 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
  • Profile defined with up to 1,024 breakpoints
  • Control on acceleration, velocity, displacement and force
  • Seamless import/export of test results into applications such as MS Word, MS Excel,
    and m+p SO Analyzer
  • Measuring and monitoring DC signals for functional testing

Sine Dwell Set-Up (incl. Resonance Search, Tracking and Phase Lock

  • Specifications as per Swept Sine
  • Dwell schedule table allows 50 dwell points to be defined
  • Each dwell can be a fixed frequency, fixed phase, peak amplitude search and track or
    defined phase search and track
  • Each dwell independently defines control (ref) and measurement channels
  • Dwell at each point for user-selectable seconds, minutes or cycles
  • User-controlled measurement data storage rate

Sine Displacement and Velocity Control

  • For sine testing starting at very low frequencies, displacement transducers can be used
  • At a defined frequency, the control changes automatically from displacement transducer
    to accelerometer transducer

Sine Data Reduction

  • Track and online analysis of taped swept sine data using the COLA signal
  • Evaluation and storage of the taped signals on a second vibration control system
    during the test run

Applications

  • Sine testing is used for proving product reliability and for structural resonance search in all
    kind of applications such as automotive, electronics, aerospace, consumer products and military
