Vibration analysis
CEVAA provides vibration analysis and expertise to identify, understand and resolve vibration-related problems in various areas.
Vibration analysis by expert engineers
CEVAA supports manufacturers in vibration diagnosis and the implementation of solutions to reduce vibrations and improve system performance. Our design office provides expertise and advice in resolving complex problems.
Thus, our team of engineers and technicians specialized in vibration analysis have a methodical and rigorous approach. We guarantee reliable and precise analysis of vibration phenomena with cutting-edge technologies and efficient software.
- Vibration measurement: on-site data acquisition using high-performance sensors and measuring instruments.
- Modal analysis: study of the modal properties of systems in the frequency domain in order to predict the in-service vibration behavior of a mechanical structure under artificial or real stress.
- Endurance testing on shakers: reproduction of accelerated vibration aging in a test center
- Numerical vibration modeling: simulation of the vibration behavior of the structure or system studied.
- Diagnosis and solutions: determination of the root causes of vibrations and proposal of corrective solutions.
Vibration measurements and testing
For vibration analysis, we have equipment such as electrodynamic shakers and structural measurement means (accelerometers).
Furthermore, CEVAA also carries out non-contact measurements and vibration characterizations using 3D scanning laser vibrometry. The advantages are the ultra-precise measurement undisturbed by the mass of the accelerometer sensors in the case of small systems to be studied or the application of a much denser mesh than with accelerometers. Operational or modal shapes make it possible to visualize compliance with specifications or to visualize defects or possible improvement of the system to be studied. In addition to this, these data measured by vibrometry and accelerometers can be used for digital model adjustment. We can also import a digital mesh to aim for an optimized calculation/test correlation.
Finally, CEVAA supports you in optimizing comfort and vibration reliability as well as in verifying compliance with the tolerance thresholds imposed by the standards. Vibration analysis by our design office provides valuable expertise for controlling vibrations and ensuring the sustainability of your installations.
