Abstract

The performance of existing ultrasonic and magnetic flux leakage techniques in detecting rail surface-breaking defects such as head checks and gauge corner cracking is currently inadequate during high-speed inspection. Moreover, eddy current sensors are adversely affected from even minor lift-off effects. Early detection of rolling contact fatigue (RCF) defects is important in order to control crack growth through sufficient and timely rail head grinding. This paper will present a detailed analysis of Alternating Current Field Measurement (ACFM) data obtained during simulated rail inspection experiments using an ACFM micro pencil probe and a TSC Amigo System to detect RCF defects.
