Electromagnetic NDT System for Inspection of Train Hollow Axles New!

Abstract. The paper presents a newly developed magnetic flux leakage transducer designated for a hollow axle testing. The transducer allows measuring three components of the magnetic residual field. Results of measurements obtained for planar and cylindrical samples with artificial defects are presented.

Inspection of Train Hollow Axles by Measuring AC Field Vector Abstract New!


Inspection of Train Hollow Axles by Measuring AC Field Vector New!

Abstract. In this paper a new electromagnetic nondestructive system for inspection of train hollow axle is presented. The system allows to observe changes of vector AC fields in order to enhance the probability of proper classification. The performance of the system is verified using hollow axle sample with artificial notches of different depths. The experimental results are presented and discussed.
