Automated monitoring system for insulated joints: Preliminary results using axle box acceleration measurements

Conference paper (2014) - M. Molodova, M. Oregui Echeverria-Berreyarza, Alfredo Nunez, Z. Li, R.P.B.J. Dollevoet

This paper presents preliminary results towards an automated monitoring system for quality assessment of insulated joints based on axle box acceleration (ABA) measurements. Longitudinal and vertical ABA signals from all the wheels of the measuring train (trailing and leading whee ...
