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
