“…By linking the wear debris and surface damage analyses, revealed the wear mechanisms transition from oxidative wear to fatigue wear and then back to oxidative wear with the increase in slip ratio. Faccoli et al [200] investigated the effect of desert sand on wear and rolling contact fatigue of the railway wheels made of ER8, CLASS C, SANFLOS* S, and SANDLOS* H, respectively. They used a two-disc testing machine with a sand feeder to measure the weight loss against rolling cycles.…”

A review of recent advances in tribology

The reach of tribology has expanded in diverse fields and tribology related research activities have seen immense growth during the last decade. This review takes stock of the recent advances in research pertaining to different aspects of tribology within the last 2 to 3 years. Different aspects of tribology that have been reviewed including lubrication, wear and surface engineering, biotribology, high temperature tribology, and computational tribology. This review attempts to highlight recent research and also presents future outlook pertaining to these aspects. It may however be noted that there are limitations of this review. One of the most important of these is that tribology being a highly multidisciplinary field, the research results are widely spread across various disciplines and there can be omissions because of this. Secondly, the topics dealt with in the field of tribology include only some of the salient topics (such as lubrication, wear, surface engineering, biotribology, high temperature tribology, and computational tribology) but there are many more aspects of tribology that have not been covered in this review. Despite these limitations it is hoped that such a review will bring the most recent salient research in focus and will be beneficial for the growing community of tribology researchers.

“…However, as reported in [8,20], intensive wear may also occur in the case of wheels of high-speed vehicles or heavy haul freight railways. Hollow wear of wheel tread is the main problem of railways in desert areas [5]. For the time being, there are neither high-speed nor heavy haul freight railways in Poland, so the main factor limiting the durability of wheels and tracks in Poland is their wear.…”

“…Sand deposition on the infrastructure can lead to the contamination of ballast, which leads in turn to the increasing of train-induced vibrations and consequently damage of sleepers, rail pads and rails [10]. It causes the jamming of turnouts, the covering of the signalling systems, the grinding of rails, the wearing of wheels [11] and train elements in general. This results in increased costs due to the repeated maintenance and loss of capacity of the line [12], i.e.…”

Background: Windblown sand mitigation for civil structures in arid environment is crucial. Indeed, the number of railways crossing deserts and arid lands is increasing. A number of sand mitigation measures already exist. Among them, sand barriers are particularly intended for line-like infrastructures. We reviewed patented sand barriers on the basis of their shape and porosity. Objective: A new solid barrier for windblown sand mitigation called Shield for Sand is presented. Shield for Sand has been designed with the aim of maximizing the sand trapping efficiency through an upper windward deflector and simplifying its maintenance by complaining to sand removal machines. The development of Shield for Sand follows the path traced by the Technology Readiness Level scale. Methods: The preliminary design of Shield for Sand has been supported by computational simulations of the wind flow around the barrier. Then, Shield for Sand has been tested in a wind tunnel with drifting sand in order to assess its efficiency. Both computational and experimental approaches allow an increase of the Technology Readiness Level. Results: The reversed flow induced by Shield for Sand increases its sand accumulation potential with respect to similar existing sand mitigation measures, such as the straight vertical wall. The efficiency of Shield for Sand resulting from the wind tunnel test is very high and almost constant with increasing sand accumulation level. Conclusion: The Shield for Sand working principles and performances are confirmed excellent. Final fullscale in-situ experiments are necessary to test the barrier under real environmental operational conditions.
