Area of Science:

Railway engineering
Structural health monitoring
Ultrasonic testing

Background:

Railway track integrity is crucial for safe and efficient rail transport.
Traditional ultrasonic methods face limitations due to electromagnetic interference (EMI) and low sensitivity to early-stage damage.
Piezoelectric sensors are susceptible to EMI in railway environments.

Purpose of the Study:

To propose and validate a hybrid ultrasonic sensing system for railway track damage detection.
To investigate the effectiveness of diffuse ultrasonic waves (DUW) for enhanced sensitivity and sensing range.
To compare damage indices based on energy attenuation and waveform distortion.

Main Methods:

A hybrid sensing system combining a lead-zirconate-titanate (PZT) actuator and a fiber Bragg grating (FBG) sensor was developed.
Diffuse ultrasonic waves (DUW), focusing on later wave packets, were employed for damage evaluation.
Controlled damages of varying sizes and locations were introduced to assess the system's performance.
Two damage indices were defined: energy attenuation and waveform distortion.

Main Results:

The hybrid system successfully detected introduced damages on railway tracks.
Diffuse ultrasonic waves demonstrated high sensitivity and a wide sensing range.
The waveform-distortion-based damage index proved more effective than the energy-attenuation-based index.

Conclusions:

The proposed hybrid ultrasonic system with DUW is a viable method for railway track damage detection.
The FBG sensor offers a robust alternative to piezoelectric sensors in EMI-prone environments.
Waveform distortion analysis provides a more sensitive metric for identifying track defects.
