Abstract
High speed videography has been successfully used to acquire failure mode images of high speed rotating machinery components. This imaging is necessary to understand failure modes in order to improve critical components and ensure overall system integrity. Work on this project started in March 1984 and is currently in progress using laser strobe lighting for surface imaging. The system used to obtain the visual data features an SP2000TM Motion Analysis System in combination with a 10 watt copper vapor laser. Two SP2000 systems with a switching unit provide a dual continuous recording capability. Three tests have been performed, each resulting in the visual recording of a failure mode at high speeds. The first recording pinpointed a part fabrication design problem, and the second and third recordings verified the effectiveness of the corrective action. Subsequent testing will incorporate a real-time x-ray system to allow simultaneous imaging of surface and internal structural elements.
