Vibration Lab

Polytec PSV-500H Scanning Laser Doppler Vibrometer.

The PSV-500H system utilizes the Doppler effect to measure time-varying velocities at a potentially large number of surface scan points on a structure, offering unique capabilities for experimental vibration analysis. It is particularly well-suited for measuring and visualizing full-field vibration patterns across various mechanical systems, as well as extracting key vibration properties such as mode shapes, natural frequencies, and damping.

With an analysis frequency range of 0–100 kHz, the system accommodates object sizes from 1 cm to several meters, a measurement distance of 0.1–100 m, and exceptional sensitivity. Its specifications in most aspects significantly outperform those of our other high-quality vibration measurement equipment.

Projects utilizing the PSV-500H include 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, and fundamental science projects such as testing competing Timoshenko beam theories.
