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

چکیده

Railway wheelsets are the key to ensuring safe operation of trains. To achieve zero-defect production, railway equipment manufacturers must strictly control every link in wheelset production process. The press-fit curve output by assembly machine is an essential indicator wheelset’s quality. operators will still need manually and individually recheck curves our practical case. However, there many uncertainties manual inspection. For example, subjective judgment can easily cause inconsistent results between different inspectors, or probability human misinterpretation increase as working hours increase. Therefore, this study proposes intelligent inspection system based on deep learning, which improves reliability efficiency solve severe imbalance number collected images, establishes a predicted model quality Siamese network. Our experimental show that precision measurement outstanding for testing dataset contained 3863 qualified images 28 unqualified curves. proposed serve successful case paradigm shift from traditional manufacturing digital manufacturing.

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...
