Modeling flexible, interconnected mechanical parts to understand their collective dynamic behavior.

Computer techniques like the Dirlik method are used in the frequency domain to estimate vibration-induced fatigue and damage over time. 3. Computer Vision-Based Vibration Tracking

The primary algorithm used to convert time-domain data (amplitude vs. time) into the frequency domain (amplitude vs. frequency), revealing discrete frequency peaks that identify specific mechanical faults.

A modern alternative to physical sensors, this technique uses video and image analysis to monitor sensitive or hard-to-reach objects.

A standard numerical procedure to identify a structure's natural frequency, which is then often validated against analytical approximations like Euler-Bernoulli beam theory. 2. Digital Signal Processing (DSP)

Techniques used to prevent "leakage" in digital signals and remove aliasing, ensuring the captured data accurately reflects reality.
