Vibration Lab
The Vibration Lab is home to a Polytec PSV-500H Scanning Laser Doppler Vibrometer capable of measuring time-varying velocities on surface scan points on a structure. This offers unique capabilities for experimental vibration analysis.
The Polytec PSV-500H Scanning Laser Doppler Vibrometer, utilizing the Doppler effect, offers:
- Analysis frequency range of 0–100 kHz
- A Measurement distance of 0.1–100 m
- Object sizes from 1 cm to several meters
- Exceptional sensitivity
The PSV-500H is utilized for research on:
- Vibration-based health monitoring (e.g. bolt tension and crack detection)
- Wind turbine blade vibrations
- Guitar body and neck vibrations
- Gas bearing shell vibration
- Dynamic substructuring
- Fundamental science projects, e.g. testing competing Timoshenko beam theories.
