Experimental and Numerical Expertise in Vibration and Acoustics

Advanced expertise in simulation and testing to design better, faster, and with greater confidence.

Master dynamic behavior to boost performance

From initial design to final validation, Metravib Engineering supports your most demanding projects with recognized expertise in numerical simulation and experimental testing.

Our skills in structural dynamics, vibration, and acoustics allow us to anticipate, optimize, and validate the behavior of complex mechanical systems before testing or industrialization phases.

By combining finite element analysis (FEA) with physical testing, we deliver reliable results that accelerate development, reduce risks, and limit prototyping costs.

Our value domains for your projects

Mechanical behavior optimization : Ensure the reliability and performance of your structures when subjected to real shocks, vibrations, and operational loads.
Control of acoustic and vibratory comfort : Reduce noise, improve user experience, and increase equipment durability.
Failure prevention : Identify critical areas and estimate service life before production.
Product validation prior to physical testing : Limit the number of prototypes, reduce costs, and accelerate development.
Global performance assurance : Guarantee the proper functioning of systems in complex, multiphysics, or highly constrained environments.

Material characterization and realistic modeling

Our characterizations are conducted in-house or through a network of specialized partners.
A simulation is only predictive if the model reliably reflects physical reality.

We perform experimental material characterization to identify behavior laws used in numerical models:

Metals, composites, polymers, elastomers, and technical foams
Hyperelastic, viscoelastic, and frequency-dependent behaviors
Determination of dynamic moduli, damping losses, and stiffness properties
Parametric identification to support finite element and vibroacoustic models

This experimental expertise ensures highly accurate material models — resulting in simulations that are more predictive and closer to real-life behavior.

The synergy between simulation and testing

Unlike many engineering firms focused solely on numerical simulation, Metravib Engineering combines experimental measurement and numerical simulation within a single technical team.
This integrated approach ensures a complete understanding of the dynamic behavior of structures.
Our activities include:

Experimental Modal Analysis (EMA): identification of natural frequencies, mode shapes, and damping
Simulation–Test Correlation: tuning finite element models based on experimental data
Operational Vibration Testing: identification of loads and boundary conditions
Shock and Dynamic Response Testing: validation of mechanical and acoustic performance

Thanks to this continuous simulation ↔ measurement loop, our clients benefit from validated, reliable, and actionable simulations for decision-making.

Custom simulation software development

Beyond standard commercial tools, Metravib Engineering designs and develops custom simulation software to address specific challenges in dynamics and vibroacoustics.
Our team of engineers and researchers combines scientific modeling and numerical development to push the limits of conventional approaches.
Some examples of our work include:

Development for CNES of a vibroacoustic boundary element method (BEM) solver to predict sound radiation and structure-acoustic coupling in lightweight space structures
Co-development with CNES of software to predict the impact of satellite microvibrations on the performance of Earth observation optical systems
Development of specific numerical modules (Python, Fortran, MATLAB) for multi-physics coupling and advanced experimental data processing

This unique ability to tailor our tools to your needs — rather than the other way around — makes Metravib both an innovation partner and an engineering service provider.

Concrete benefits for your developments

Application examples

Our expertise is applied across multiple industrial sectors:

Aerospace & Space: Modal analysis of composite structures, resistance to pyro-mechanical shocks, acoustic qualification of payloads, support for the development of elastic suspensions.
Rail & Mobility: Support for the development of components exposed to random vibrations and shocks according to normative specifications (thermoplastic parts, railway components, traction transformers, HVAC groups, LED lighting systems, etc.).
Defense & Security: Shock resistance studies, design of dynamic isolation and protection systems.
Energy & Offshore: Vibratory fatigue of structures subjected to waves and wind, fluid-structure coupling, acoustic and vibration studies of O&G structures for compliance, comfort, and occupational hygiene on floating structures (FPSO) and oil platforms.
Instrumentation & Industrial Machinery: Vibroacoustic performance of precision equipment, operational noise analysis, rotor dynamics analysis and fatigue of electric motor components.

Each project demonstrates our ability to model complex phenomena, validate results through testing, and turn simulation into a true decision-making tool.
