Sectors of application
Industrial structures subjected to vibratory excitation in the energy and transport sectors (automotive, aeronautical, railway, maritime)
Your challenges
- To control the vibratory behaviour of your industrial equipment that is subjected to multiple mechanical excitation
- To optimise vibration reduction solutions
- To carry out experimental validation of prototypes
- To carry out experimental validation of digital models
Our strengths
Experimental know-how proven through numerous test campaigns on our production sites- Expertise in both digital and experimental vibration diagnosis, currently used to ensure the availability of EDF equipment
- Internationally recognised scientific excellence (publications, awards, higher education) in support of studies by EDF’s engineering division
Our offer
- Performance of vibration tests on industrial installation structures and equipment:
- Equipment/structures weighing several tonnes
- Multiple excitation points (shock hammers, shaker units)
- Variety of sensors (laser velocimeter, accelerometers, gauges, etc.)
- Large number of measuring channels (>200)
- Analysis/use of data
- Modal analysis
- Measurements during operation (ODS)
- Post-processing in relation with digital models
- Correlation of calculations/tests
- Recalibration of models, etc.
