Mechanical Engineering.

As mechanical experts, we support your projects in design, calculations, and numerical simulation.

Our expertise covers solid mechanics, kinematics, vibrational mechanics, acoustics, thermal engineering, and fluid mechanics.

Our know-how also extends to associated testing (organization, monitoring, etc.), in order to provide complete technical solutions tailored to your needs.

Acoustics.

Acoustic signal processing.
Development of acoustic and thermo-acoustic test benches.

Structural analysis and mechanical design.

Numerical modeling: CAD, drafting, model simplification, defining contacts, boundary conditions, and loads, Finite Element discretization.
Structural analyses: static, dynamic, vibrational, nonlinear, thermal.
