“…Approaching this electromagnetic field with a conductive metal creates a current in the conductive metal. Assessing the potential drop related to this sort of derived current is the basis of the induced current focusing potential drop technique discussed in Kwon et al 24 Several artificial railway wheel defects were applied and then this method was used to detect the surface and sub-surface cracks. These non-destructive tests show that induction wires (of about 40 mm in length) must be positioned at a certain distance from the crack (5 mm distance) to be able to detect the cracks.…”

Condition monitoring systems are commonly exploited to assess the health status of equipment. A fundamental part of any condition monitoring system is data acquisition. Meaningfully estimating the current condition and predicting the future behaviour of the equipment strongly depends on the characteristic of the data measurement stage. Nowadays, condition monitoring has wide applications in the railway industry and various monitoring approaches have been proposed for the inspection of wheel and rail conditions. In-service condition monitoring of wheels provides the real-time data required for maintenance planning, while in-workshop inspection is normally done at fixed intervals carried out periodically. In-service data acquisition can be divided into on-board and wayside measurements. In this paper, on the basis of these classifications, the existing data acquisition techniques for the monitoring of railway wheel condition are reviewed, and the state-of-the-art methods and required research are discussed.

“…According to the geometric characteristics of the cracks, they can generally be divided into penetration cracks, deep buried cracks and surface cracks. [24][25][26] Penetration cracks refer to cracks penetrating through components and are usually treated as ideal tip cracks. Deep buried cracks refer to cracks inside components, often simplified as elliptical or circular cracks.…”

The influence of braking sequence on railway brake disc's radial crack propagation behavior is analyzed considering the effect of crack geometry features, material elastoplasticity, and crack closure. The results show that when the residual stress generated in the initial braking is low, the peak stress in the subsequent braking will be low, and the average response state is more inclined to compression. The influences of the braking sequence are mainly reflected in the mid‐late stage of crack growth. In the early stage, the radial cracks almost synchronously expand inward and outward. While in the mid‐late stage, the cracks mainly expand inward. When the initial braking is relatively mild, the brake disc's stress–strain response and crack propagation behavior can be improved. It is beneficial to extend the brake disc's service life by designing a suitable prefabricated working condition or introducing an appropriate residual stress field through surface treatment.

“…In-service measurements can be further divided into two types based on the position of the data acquisition sensor: onboard measurements and wayside measurements. Ultrasonic techniques [20,21], infrared camera [22], and magnetic techniques [23][24][25] are commonly used monitoring tools used during in-workshop measurements of rail wheels. Acoustic techniques [26,27], ultrasonic technique [28], vibration measurements [29,30], and magnetic techniques [31,32] are common types of monitoring techniques used for in-service and onboard inspections of rail wheels.…”

Evaluation of Measurement Strategy for Track Side Monitoring of Railway Wheels

et al. 2023

Wheelsets form an indispensable part of the railway rolling stock and need to be periodically inspected to ensure stable, safe, reliable, and sustainable rail operation. Wheel profiles are usually inspected and measured in a workshop environment using handheld equipment or by utilizing wayside measuring equipment. A common practice for both methods is to measure the wheel profile at one position along the circumference of the wheel, resulting in a one-slice measurement strategy, based on the assumption that the wheel profile has the same shape independent of the measurement position along the wheel. In this article, the representability of a one-slice measurement strategy with respect to the wheel profile parameters is investigated using handheld measurement equipment. The calculated range of standard deviation of the parameters estimated such as flange height, flange width, flange slope, and hollow wear from the measurements shows a spread in the parameter value along the circumference of the wheel. As an initial validation of the results, measurements from the wayside monitoring systems were also investigated to see if a similar spread was visible. The spread was significantly higher for flange height, flange width, and flange slope estimated from wayside measurement equipment than for the same parameters estimated using the handheld measurement equipment.
