Train wheelset is one of the most important and costly-on-maintenance components in the
rolling stock. Timely assessment of the wheelset wear can prevent the wheelset wear …

Reliable monitoring and assessment of wear evolutions are critical for performing effective
railway maintenance. Several characteristics and variables are used to quantify a worn …

Pantograph slider is the critical component to provide power for the train. The friction
between the slider and the contact line will lead to the continuous wear of the slider. Timely …

This paper focuses on the adjustment of B-spline approximation to terrestrial laser scanning
(TLS) data and its contribution to deformation analysis of composite arched structures. The …

Wheelset geometric parameters, such as the flange height and wheel diameter, are of great
significance for detection to ensure the operational safety of trains. In this article, an efficient …

Line laser scanning is an effective method used to measure the 3D shape of machined
honeycomb core surfaces. The lack of laser-sensor calibrations in 3D space relative to the …

The maintenance of railway systems is critical for their safe operation. However some
landscape geographical features force the track line to have sharp curves with small radii …

The real-time monitoring of wheel size is important technology in ensuring the normal and
safe operation of railways. Meanwhile, online dynamic measurement equipment based on …

Railway wheels are one of the important parts of railway vehicles, and it is necessary to
inspect their status frequently. To measure the wheel tread geometric parameters …

Wheel diameter is a significant geometric parameter related to the safe operation of trains,
and needs to be measured dynamically. To the best of the authors' knowledge, most existing …
