Mécanics.
As experts in mechanical engineering, we cover acoustics, calculations, numerical simulation, and mechanical design.
Our expertise
Our expertise also includes vibration analysis and related testing (organization, test monitoring, etc.), enabling us to provide comprehensive, customized technical solutions tailored to your needs.
Acoustics.
- Acoustic impact studies: on-site measurements, numerical simulations, diagnostics, advice, and support.
- Internal acoustic and vibro-acoustic comfort for all types of vehicles (measurements, numerical simulations, acoustic treatment solutions).
- Aeroacoustic numerical simulations (acoustic signature of an aircraft, turbomachinery, landing gears, CFD/CAA coupling).
- Acoustic signal processing.
- Development of acoustic and thermoacoustic measurement benches.
Structural analysis and mechanical design.
- Numerical modeling: CAD, drafting, model simplification, defining contacts, boundary conditions, and loads, Finite Element discretization.
- Structural analysis: static, dynamic, vibrational, nonlinear, thermal.
- Design and manufacturing of operational prototypes.
- Preparation of technical drawings and calculation reports.
- Test-to-simulation correlation and model adjustment.
Vibration studies.
- Linear or nonlinear calculations based on transient or steady-state excitation (shock, seismic, harmonic, random).
- Vibration fatigue calculations and lifetime estimations.
- Experimental modal analysis (instrumentation and analysis).
- Material and fluid characterization using vibratory methods.
- Development of vibration damping systems (specifications, numerical simulations, custom test bench development, and validation tests).
- Validation, robustness, and fatigue vibration tests.
- Multi-axis vibration testing on 6-axes hydraulic shaker (Equipex PHARE-3).
Fluid mechanics.
- Aerodynamic studies of internal and external flows on vehicles and propulsion systems.
- Numerical simulations in aeroelasticity (fluid-structure coupling).
- Analysis of interactions between fluid mechanics and heat transfer by conduction, convection, and radiation.
Tri-axial laboratory testing / Tri-axial test platforms.
