Faced with the acceleration of the energy transition and growing demands for reduced emissions, Vibratec has been a trusted partner for more than 15 years in mastering the acoustic and vibratory challenges of electrified powertrains.
We are involved from the earliest design phases to secure your technical choices, reduce NVH risks and guarantee a robust, high-performance design right from the start.
Electric vehicles have to meet high expectations in terms of acoustic comfort. Vibratec helps you eliminate engine whistling and gearbox siren noise right from the design phase.
We support hybrid propulsion projects with a global approach to overall dynamics and mechanical reliability.
We optimize sound comfort, both inside and outside vehicles, in all operating phases.
We reduce noise pollution at source, for a more pleasant environment that meets customer specifications.
NVH performance under control
01

Proprietary software tools
VibraVolt and VibraGear, developed with our research partners.
Developed by Vibratec, VibraVolt is a software tool designed to simulate and optimize the acoustic behavior of electrical machines. It combines electromagnetic, mechanical and acoustic models to accurately anticipate vibration sources and noise levels generated by electric motors or generators.
Thanks to this multiphysics approach, VibraVolt is a powerful solution for reducing noise pollution right from the early stages of product development..
VibraGear is a software tool developed by Vibratec in collaboration with the École Centrale de Lyon.
It enables detailed study of the internal sources of gear excitation – such as static transmission error or variations in mesh stiffness – and evaluation of their vibratory response using imported finite element models.
With VibraGear, engineers have a powerful solution for designing gearboxes that are quieter, more reliable and offer better performance.
01
A complete system vision
We integrate all sources of noise and vibration in their real-life environment (motors, gears, solid-borne and airborne transfers).
02
Cutting-edge digital tools
Electromagnetic, mechanical and multi-body models, taking into account non-linearities and manufacturing tolerances.
03
Robust, optimized solutions
Noise reduction at several operating points, without compromising performance (efficiency, torque, weight, etc.).
04
Smooth collaboration with your teams
Our experts speak the language of your electromagnetic, mechanical and control system engineers.
