“…In Na et al [ 308 ], the authors examined the contact condition of the energy supply system. This contact was certainly associated with a pantograph and an overhead contact line, and the authors analyzed it via image processing implemented using a device installed on a rail vehicle’s roof; this device included fiber-optic sensors .…”

Condition monitoring of rail transport systems has become a phenomenon of global interest over the past half a century. The approaches to condition monitoring of various rail transport systems—especially in the context of rail vehicle subsystem and track subsystem monitoring—have been evolving, and have become equally significant and challenging. The evolution of the approaches applied to rail systems’ condition monitoring has followed manual maintenance, through methods connected to the application of sensors, up to the currently discussed methods and techniques focused on the mutual use of automation, data processing, and exchange. The aim of this paper is to provide an essential overview of the academic research on the condition monitoring of rail transport systems. This paper reviews existing literature in order to present an up-to-date, content-based analysis based on a coupled methodology consisting of bibliometric performance analysis and systematic literature review. This combination of literature review approaches allows the authors to focus on the identification of the most influential contributors to the advances in research in the analyzed area of interest, and the most influential and prominent researchers, journals, and papers. These findings have led the authors to specify research trends related to the analyzed area, and additionally identify future research agendas in the investigation from engineering perspectives.

“…Fatigue failures are prone to occur across a hard beam middle, and components are easily damaged. (2) After modal analysis, the portal structure natural vibration frequency is only between 1.586683-180.5974, and the first four-order mode shape is a curved mode, which is gradually converted into torsional vibration as the frequency rises. Compare experimental and simulation data.…”

“…The catenary system is the core part of electrified railway, the stable contact and interaction between the pantograph and contact line is also the most important condition for safe power supply. The stability and safety of catenary portal structure is the important condition to ensure good train operation [2]. The stability and safety of catenary power supply of electrified high-speed railway lines can be effectively guaranteed by doing a good job in the research of catenary portal structure vibration [3,4].…”

The portal structure is the support equipment in the catenary, which bears the load of contact suspension and support equipment. In practical work, with the change of external forces, the support equipment bears complex and changeable loads, so it has higher requirements for its reliability and safety. In order to study the dynamic characteristics of catenary portal structure on continuous beam of four-way bridge, taking the catenary portal structure on Dshaping four-way bridge as the research object, the portal structure simulation model of bridgenetwork integration was established in Midas Civil. The maximum point of deformation and stress was determined by finite element analysis of catenary hard span equipment, and the frequency and mode of natural vibration of hard span were obtained by modal analysis. Secondly, through the field dynamic stress acquisition test, combined with the results of finite element analysis, the fault location is determined, and the vibration characteristics are analyzed. Finally, based on the results of modal analysis and vibration analysis, the method that the vibration of portal structure beam is affected by structural stiffness and vibration frequency amplitude is proposed. The torsional vibration of the portal structure beam was suppressed by increasing the stiffness of the beam and reducing the vibration conduction between the trolley and the beam, and the hard cross beam was optimized by strengthening the hanging column and the connecting beam and adding diagonal support between the pillar and the portal structure beam. By comparing the values of shear, bending moment, displacement and dynamic stress on the hard span before and after optimization, the amplitude peak after structural optimization is reduced by about 25%, and the application of oblique support and reinforcement of the beam can significantly improve the portal structure vibration.

“…Most of these papers are authored by Aydin Firat University, Turkey. However, in research published in and after 2017 [56][57][58][59][60][61][62][63][64], researchers began to use camera sensors and deep learning-based computer vision techniques. "Contact point" and "contact force" account for 11.1% of the total amount, after "supportive components" and "arc".…”

In this paper, a different approach to the traditional literature review—literature systematic mapping—is adopted to summarize the progress in the recent research on railway catenary system condition monitoring in terms of aspects such as sensor categories, monitoring targets, and so forth. Importantly, the deep interconnections among these aspects are also investigated through systematic mapping. In addition, the authorship and publication trends are also examined. Compared to a traditional literature review, the literature mapping approach focuses less on the technical details of the research but reflects the research trends, and focuses in a specific field by visualizing them with the help of different plots and figures, which makes it more visually direct and comprehensible than the traditional literature review approach.
