Vibratec’s activities, focused on mechanics, and more particularly on acoustics and vibrations, revolve around a number of different disciplines:

  • structure and system dynamics, vibroacoustics and signal processing
  • digital simulation and experimental analysis for services ranging from design to diagnosis for a high level of reliability of calculations.
  • digital and computerized methods enable Vibratec, and its subsidiary MicrodB, to develop experimental analysis tools for 3D acoustic imagery (complete systems – software & hardware) and identification of vibratory sources (inverse method techniques) and simulation tools, in particular for acoustic calculations.

– Development of 3D acoustic imagery measurement systems and calculation software (generic or product-specific)
– Design of vibration control solutions or processes.

Concrete examples of applications

– Vibratory diagnosis of machinery on a drilling barge. Creation and adjustment of a calculation model for assessing potential solutions. Implementation and validation of solutions
– Calculation and measurement of the vibratory behaviour of automobile bodywork. Resetting of measurements using large Finite Element models followed by application to optimize the vibro-acoustic response rate of the vehicle. Experimental and digital approach to develop a method for measuring catenary pantograph contact force on high-speed rail networks
– Acoustic imagery system for identifying source fields on incoming aircraft: this technique makes it possible to pinpoint the aerodynamic sources on the aircraft
– Development of a medium frequency acoustic calculation code for optimizing the acoustic baffle of an industrial vehicle for the comfort of other road users and for the driver and passengers
– Design and delivery of dynamic absorbers for reducing pipe vibration and stress so as to minimize the risk of cracking.
