Mixed Mode Testing

The Mixed Mode add-on modules for the Random Vibration Control Software allow tests to run with sine tones and/or narrowband random signals superimposed on a random background. Mixed mode testing is a complex control task, and VibControl supports three modes: Sine-on-Random (SoR), Random-on-Random (RoR) and Sine-on-Random-on-Random (SoRoR). Gunfire burst control can also be superimposed in each case.

Key Features

• SoR and RoR control are fully compliant with DIN, MIL-STD 810 and other standards
• Support on electrodynamic and hydraulic shakers
• Up to 20 independently sweeping sine tones and/or 25 narrowband random signals
  overlaid onto a random background
• Each sine tone/narrowband with its
  own profile and limits
• Time offset and automatic timed toggle on/off
  for each individual sine tone/narrowband
• Gunfire burst simulation
• Overlapping of the sine tones/narrowbands
• Accurate control thanks to independent sine tone generators and digital tracking filters
  

Applications

• Tracked and wheeled vehicle vibration (helicopter, turbo jet aircraft, automotive power train),
  trains, agriculture vehicles
• Machine gunfire simulation
