For low-frequency tests requiring a significant displacement (vehicle body movement) or even to go down to 0.1Hz (marine tests), we have a set of electrohydraulic vibration generation.

  • Maximum acceleration: 15 gn
  • Velocity sine peak: 0.7 m/s
  • Displacement continous: 100 mm peak-to-peak


For very high frequency tests, it is necessary to use piezoelectric vibration generating means.

We have 2 generator sets of 4 kN and 30 kN covering a range from 1000 Hz to 10 kHz with a maximum displacement of 20µm peak-to-peak.

 

 

Vibrations multiaxes

We have up to 3 axes of control which allows us to control up to 3 vibrators (electrodynamic or electrohydraulic) simultaneously.

Driving is done in sinus, random, or recopy of road signals, and on force, displacement or acceleration signals.
