Abstract EN
Nondestructive evaluation (NDE) of steel cables in long span bridges is necessary to prevent structural failure.
Thus, an automated cable monitoring system is proposed that uses a suitable NDE technique and a cable-climbing robot.
A magnetic flux leakage- (MFL-) based inspection system was applied to monitor the condition of cables.
This inspection system measures magnetic flux to detect the local faults (LF) of steel cable.
To verify the feasibility of the proposed damage detection technique, an 8-channel MFL sensor head prototype was designed and fabricated.
A steel cable bunch specimen with several types of damage was fabricated and scanned by the MFL sensor head to measure the magnetic flux density of the specimen.
To interpret the condition of the steel cable, magnetic flux signals were used to determine the locations of the flaws and the levels of damage.
Measured signals from the damaged specimen were compared with thresholds that were set for objective decision-making.
In addition, the measured magnetic flux signals were visualized as a 3D MFL map for intuitive cable monitoring.
Finally, the results were compared with information on actual inflicted damages, to confirm the accuracy and effectiveness of the proposed cable monitoring method.
