Many familiar mechanical systems such as engines, powertrains and gearboxes generate rotational motion and transmit torque, movement, speed, and acceleration from one place to another. Thus these systems are significant sources of rotational vibration.
Non-contact measurements help to cope with undesired vibrations. Due to their flexibility, laser vibrometers are utilized in the R&D process, but are also a good tool for troubleshooting.
Laser vibrometry covers the three main applications:
- Torsional vibrations in shafts
- Bending vibrations in shafts
- Axial deflection shape measurement on rotors
