Vibration measurement

Why Vibration Analysis?

Interest: Allows the control of 4 expectations / product benefits:

• Noise (e.g. automotive, etc...)
• Pleasantness (e.g. transmission, suspension)
• Lifetime (e.g. valve)
• Operating safety (e.g. bridge, building, seismology, etc.)

Principle of vibration analysis

• High dynamic measurement + frequency analysis

• identify eigenmodes experimentally
• ensure that the eigenmodes are controlled

Some fields of application of vibration analysis

• Railway
• automotive
• Aeronautics
• Production
• Energy

Possible approaches to vibration measurement

• high frequency displacement measurement
• acceleration measurement
