Asia Turbomachinery & Pump Symposium

Our Senior Staff Engineer, Stephen Price, recently represented EDI at the 2022 Asia Turbomachinery & Pump Symposium. During this time, he shared a tutorial to provide some technical basis for the video technique and examples from the field using both ODS and MAV to help users evaluate their relative strengths and weaknesses.

Operating Deflection Shape (ODS) testing that was derived from Experimental Modal Analysis in the 1980s has served well to assist users in quantifying vibration amplitudes, determining vibration mode shapes, mechanical integrity, the most effective locations and directions to add stiffness, and identifying cracks in beams and foundations.?A recent technique that provides amplified motion from video (MAV) has become accepted that can do much the same with considerably less effort.?However, each technique has its own limitations and range of applicability.
