Abstracts:
Objective: Rail wear detection for urban rail transit is a crucial approach to studying rail defect development and ensuring operational safety. To address complex disturbances such as train swaying, abnormal reflections, and foreign object obstructions, achieve precise rail wear measurement, the rail full sectional profile detection system（abbreviated as RFPD) is optimized in design and studied. Method: The measurement principle of RFPD is briefly described, and the system design is optimized. Software in RFPD is developed, including ones for extraction and data analysis of rail full sectional profile. Manual measurements are performed on 22 rail segments with varying curve radii and degrees of rail wear across Guangzhou Metro Lines 1, 2, 3, 4, 5, 8, and 14. The accuracy and repeatability of the measurement results from RFPD are compared and analyzed against the manually measured results. Result & Conclusion: The rail wear measurement results from RFPD align with the onsite manually measured results. The system meets the requirements for measurement accuracy and repeatability, thus fulfilling the needs of rapid and dynamic wear detection for urban rail transit lines.
