“…Methods from the non-destructive testing group and quality management tools were used in the model because they are preferred in casting quality control and quality problem analysis. Many cited literature items confirm the effectiveness of applying the considered methods individually [ 41 , 85 , 86 , 87 , 88 , 89 , 90 , 93 , 94 , 95 , 96 , 97 ].…”

“…The overriding aim of non-destructive testing is primarily to detect inconsistencies that have the character of discontinuities of material. The use of non-destructive testing in the proposed model is also justified by safety considerations and the economic aspect of an unforeseen failure [ 25 , 26 , 27 , 28 , 29 , 41 ].…”

“…These studies show how advances in technology have broadened the application of non-destructive testing even in industries that may not be manufacturing-oriented, noting that NDT is not limited to anomaly detection. Although advances have improved the way testing is performed and increased the benefit from its use, it is essential to remember that these techniques are primarily manual and rely heavily on the knowledge and experience of inspectors, which leaves room for error [ 41 ]. Therefore, more and more often, the authors of studies pay attention to determining the optimal design of castings in the context of facilitating the implementation of non-destructive testing tests with specific methods [ 42 ].…”

An essential element of any industry is castings, which is determined by the technical conditions for their reception. However, conducting production in the foundry technology is burdened with many difficulties associated with, for example, the inability to control all of the parameters that may affect the casting quality. Therefore, it is essential to undertake improvement actions in this area. Efforts are being made to use non-destructive testing (NDT) as a part of quality control, but these methods are rarely combined in a single diagnostic run. As a part of quality improvement, it is also essential to identify the root cause of the problem. For this reason, it is justified to develop a model of diagnosing and searching for non-conformities, which would combine NDT tests and quality management tools. The model included the visual, ultrasound, and eddy current examination in the diagnostic part, and the Pareto–Lorenz diagram correlated with ABC method, histogram, and 5WHY method (asking five questions why). The study’s originality is manifested in the combination of several NDT methods with quality management methods in one model. Using integrally configured methods in the proposed model, it was possible to: reduce diagnostic uncertainty, characterize the critical group of non-conformities, and identify the root causes of the quality problem. The model is a new and universal method that can be implied in any foundry company in order to ensure the stability of the production processes. The application of the model contributes to an increase in the detection speed and enables the reduction of non-conformities in aluminium castings, thus increasing the quality level of the offered products.

“…In railway system, different techniques and sensors are utilized, which includes Alternate Current Field Measurement (ACFM), radiography, Electro Magnetic Acoustic Transducers (EMATs), AE, Magnetic Flux Leakage (MFL), Eddy Current (EC), Ultrasonic Testing (UT), etc. [19]. These sensors can detect a wide range of faults, discussed in section I (A).…”

State-of-the-Art Wayside Condition Monitoring Systems for Railway Wheels: A Comprehensive Review

et al. 2023

View full text Add to dashboard Cite

In recent decades, there has been a constant demand for faster, longer, and safer railway networks. This also brings challenges for condition monitoring systems in modern railway vehicles. More specifically, critical parts of railway vehicles like wheels degrade over time due to various operational and environmental reasons. Different dynamic effects such as skidding/sliding over the track and the presence of contamination between wheel-rail cause various wheel defects. Faulty wheels ultimately lead to the derailment of railway vehicles. To avoid worst situations like railway derailments, various research has been conducted for developing efficient condition monitoring systems for railway wheels. In addition, there have been some commercial condition monitoring products that can be deployed with railway vehicles. These systems incorporate various sensors such as strain gauges and vision sensors to collect data for diagnosis and prognosis. Various methods have been explored but yet there is a broad research gap in terms of developing advanced onboard condition monitoring systems. With the progress in technology, advanced systems with Machine Learning/Deep Learning methods can provide more efficient and robust condition monitoring of dynamic railway systems. Considering the need for advancement in condition monitoring systems for railway vehicles, a comprehensive review of existing condition monitoring systems for railway wheels is conducted in this paper. The review is aimed at understanding the feasibility and potential of new methods for modern railways. This paper provides a detailed overview of studies on the existing wayside systems and reports their advantages and disadvantages concerning its recently emerging counterpart on-board monitoring systems. Data acquisition systems and analysis methods are critically reviewed which could assist in developing more efficient and reliable condition monitoring systems for railway wheels. This article also reviews the current progress of wayside systems and their limitations. The article is targeted at the researchers and engineers working in this domain, who can pave the way for developing advanced and cost-effective condition monitoring systems for railway wheels using modern technologies.

The paper is concerned with development of the asymptotic formulation for surface wave field induced by vertical surface stress under the effect of gravity in the short-wave region. The approach relies on the methodology of hyperbolic-elliptic models for the Rayleigh wave and results in a regularly perturbed hyperbolic equation on the surface acting as a boundary condition for the elliptic equation governing decay over the interior. A special value of the Poisson’s ratio v = 0.25 is pointed out, at which the effect of gravity disappears at leading order.
