Acoustics and measurements
Discretion and vibro-acoustic comfort / vibration reduction
- Characterization of dynamic (modulus of elasticity, damping) & acoustic properties of composites
- Noise and vibration diagnosis on board ships
- Acoustic insulation of bulkheads and decks
- Vibration analysis and diagnosis of propulsion and auxiliary equipment
- Operational deformations of structures
- Vibration isolation of machines, definition of suspension systems
- Torsional vibrations, eigenmodes
Measurements on site or at sea
- Vibration measurements
- Acoustic measurements
- Deformation measurements by strain gauges on hulls and superstructures
- Measurements of back pressure, flow rates, exhaust pressure drops
- Hull pressure fluctuation measurements
- Torque measurements on shaft lines, power calculation
Testing and simulation
Environmental testing of products
Qualification and validation of composites parts
- Environmental testing: climatic tests, sealing (spray, immersion) and salt mist (corrosion – saline atmosphere of water)
- Vibration testing
- Transport and mechanical testing
- Electric battery tests
Simulation, calculation and 3D modeling
- Design simulation
- Multiphysics simulation : fatigue calculations, acoustic calculations (indoor noise, airborne noise, structure-borne noise), vibration calculations, stress resistance calculations, shock, impact, CFD / fluids (hydrodynamics)
- Specific calculations (torsion modes, anti-vibration sizing)
- Creation of material maps for rapid static and dynamic simulation (impact/crash)
- CAD design and 3D modeling, structural dimensioning
Materials analysis
Identify the origin of the failure
Material failure expertise
Application cases
- Acoustic and vibration analysis on a Ferry
Context: The ferry crew complained about noise pollution in their cabins coming from the ship’s galleys (high noise level at low frequency).
Realization: Vibro-acoustic measurements in several cabins and in the galley - Vibration measurements of a detection system on a military ship
- Failure expertise on parts
Responses to specifications to validate new coatings (salt spray corrosion test) and validation of materials by chemical analysis ICP/SEO + LECO
