“…The treads revealed fine microscopic cracks, as shown in Figure 3 and Figure 4. The cracking mechanism is similar to that discussed by Lewis and Olofsson (2009); where the wheel surface experiences deformations as a result of cyclic loading, leading to crack initiation which ultimately results in the loss of particles from the surface. Lewis et al (2003) described this phenomenon as 'ratcheting'.…”

“…This plastic deformation and fatigue crack-related detachment forms hollow wear within the wheel/rail interface and progresses over many rolling contact cycles. Lewis and Olofsson (2009) stated that 'severe wear results in a rough, deep torn surface -much rougher than the original metallic wear debris, typical of up to 10 m'. It was further indicated that there is a Effect of yield strength on wear rates of railway wheels by V.J.…”

“…However, the word adhesion has become widely used among the wheel-rail research community to describe the tangential force resulting at the wheel-rail contact as used in [34,35]. Friction force is defined as the resistance encountered by one body moving over another body [36]. Figure 20.…”

The wheel-rail contact is a safety critical interface. Wear, particle emission and adhesion are all wheelrail contact phenomena and are discussed here. All three phenomena are material and system parameters and are linked together. Different countermeasures to one phenomenon such as adhesion enhancement with a friction modifier can increase the wear in the contacting bodies. The wear of railway wheel and rail are linked to the number of airborne particles generated, but the exact number and size distribution of the aerosols is unknown. The main objective of this study is to review recent work in this field and to discuss future trends.

Abstract. Wheel wear is one of the major costs in railway tracks consisting of sharp curves. In this paper, wear behavior of S1002 pro les of wheels in the \Southern Line" of Iran's railway, which consists of a large number of distinct and/or consecutive sharp curves, is studied using the eld data measuring technique. Based on wear behavior analysis of all wheels, an optimal wagon maintenance technique called the \ rst and second limits" is suggested to minimize the wagon's cost per traveled distance. The results show that: 1) A severe wheel ange wear occurs for all wheels in comparison to the wheel tread wear in normal tracks; 2) A wagon's detachment for repair of critical wheels on its four axles occurs at the traveled distances of 40,000 km, 54000 km, 71000 km, and 75000 km, respectively (much less than the normal traveled distance of 500,000 km); 3) A fth order polynomial function can be appropriated to represent the wear behavior of the wheels; 4) By implementing the suggested technique, the cost per traveled distance decreases by 38.64%, and the travelled distance increases by 45%.
