A Novel Sensor Concept for Structural Health Monitoring of Rotating Machines
The objective of the investigator of this project is to investigate guided wave based non-destructive testing (NDT) methods for real time monitoring of rotating shafts as an alternative or complementary solution to existing vibration based methods. It is proposed that ultrasonic based methods would operate more effectively in detecting fatigue damage than current vibration based methods. Therefore, the investigator’s purpose to investigate a sensor strategy utilizing externally generated magnetic fields to create elastic stress waves within moving shafts using the magneto-elastic coupling effect. Ideally, the sensor will allow for non-contact operation at a considerable RPM for real-time fatigue damage evaluation. The proposed sensor may prove vital to NASA and commercial applications requiring health monitoring of rotating shaft components.
