CSP03 - Motion Amplification Case Study: Relative Motion between Components

Abstract

This case study shows how Motion Amplification video has been used to contribute to identifying the root cause of a seal issue. Motion amplification is a video-processing product and software that detects subtle motion and amplifies that motion to a level visible with the naked eye. The technology turns the cameras recorded pixels into a sensor and is capable of measuring vibration or motion with high levels of accuracy. This technique enabled the Diagnostics Engineer to home in on the issue. Waveform and spectral data captured from Motion Amplification videos was then used to develop an understanding of the motion and determine the next steps. The analysis was accepted and currently a structural analysis is undergoing as recommended by the initial study. We discuss the particular advantages of the technology and the limitations encountered in this case.
