Wheel maintenance in rolling stock: safety challenges in the defect detection process

“…Aside from the figures that reveal the criticality of maintaining wheel cracks, wheel maintenance is also crucial (Zhang et al, 2014;Singh and Kumar, 2015), as wheels constitute a large part of the rolling stock (Palo et al, 2013) and because they suffer from deterioration with usage and age (Zhang et al, 2014). The wheel profile determines the stability of a vehicle, and the rate of wheel surface wear determines the length of a wheel's life, as well as its behaviour.…”

“…Moreover, it presents the procedure that the authors followed in order to create the corresponding flowchart. The aim is to show the various stages of defect inspection and detection, along with the paths through which inadequate manipulations -both from humans and automated systems -may occur and, in turn, lead to safety risks, impacting at the same time the safety (Zhang et al, 2014) of the entire system, like in the case of derailments (Singh and Kumar, 2015).…”

“…Previous literature on wheel maintenance primarily concerns the profile of the wheel in terms of damage tolerance and fatigue (Gerdun et al, 2007;Zerbst et al, 2005), geometry (Zhang et al, 2014) and fracture mechanics (Zerbst et al, 2005). With this regard, Singh and Kumar (2015) evaluate human error probability in order to reduce the likelihood of errors occurring within a system. Singh and Kumar (2015) highlight elements of the system (bogie, wheel-set etc.)…”

“…With this regard, Singh and Kumar (2015) evaluate human error probability in order to reduce the likelihood of errors occurring within a system. Singh and Kumar (2015) highlight elements of the system (bogie, wheel-set etc.) and discuss how a decline in human performance may lead to errors in maintenance tasks.…”

Human reliability assessment (HRA) in maintenance of production process: a case study

“…Maintenance process of complex industrial technology is noted as being especially vulnerable to human error; and, human error have a high contribution in maintenance cost profile of production plants (Kirwan and Ainsworth, 1992). Human errors in maintenance activities may generally lead to incorrect decisions, actions, or checks (Singh and Kumar, 2015). Mannan (2012) and Castiglia and Giardina (2013) demonstrated that human error is the primary causal factor of between 50% and 90% of the accidents in industries.…”
