Intelligent System for Railway Wheelset Press-Fit Inspection Using Deep Learning

Railway Wheelset Parameter Estimation Using Signals from Lateral Velocity Sensor

A type of parameter estimation technique based on the linear integral filter (LIF) method, the least-absolute error with variable forgetting factor (LAE+VFF) estimation method, is proposed in this paper to estimate the railway wheelset parameters modelled as a time-varying continuous-time (C-T) system. The inputs to the parameter estimator are the control signal and the railway wheelset system ...

Railway track inspection using GPR

Ž . Swiss Federal Railways SBB inspect their railway tracks at regular intervals. The first step of track renewal planning is a geotechnical study. Inspection is focused on the thickness of the ballast, on subsoil material penetrating upwards into the ballast and on geotechnical properties of subgrade and subsoil materials. Up to now, the inspection has been done mainly by digging trenches at e...

Fault Tolerant Strategy for Actively Controlled Railway Wheelset

this paper studies the key issue of fault tolerance for actively controlled railway wheelsets. It assesses failure modes in such systems, with a focus on actuator failures, and consequence of those hardware failures. It seeks to establish the necessary basis for control reconfiguration to ensure system stability and performance in the event of a faulty, without the need for hardware redundancie...

Automated System for Magnetic Particle Inspection of Railway Wheels

This paper presents a new developed automated system used for flaw detection and classification on railway wheels. The described system uses the principle of non-destructive method based magnetic particle inspection. Our proposed and finally constructed automated system is used in industrial applications where non-destructive testing of railway wheels is desired. As a part of testing line, it i...
