“…The cracks that are generated by contact fatigue, however, do not lead to overall wheel failure, but rather are precursor to localized damage, often referred to as shelling. 22 The recorded strains are much smaller than the ultimate strains under static loading reported by Muzyczka 13 indicating that while the cast iron roller was designed with a safety factor of almost 2.5, the presence of cyclic loading deteriorated its structural performance. Due to the unpredictability nature of the fatigue life of such rollers, it is recommended that their use be curtailed in the future.…”

“…Even though this spall is small, it would grow in size until roller fracture would occur, as bearing operation continues. 19 Sciammarella et al 22 conducted an experimental evaluation of rolling contact fatigue (RCF) in railroad wheels and reported that cracks due to contact fatigue lead to a damaging phenomenon called shelling. This phenomenon has actually been observed in a number of spillway gates operated by Manitoba Hydro, 13 as shown in Figure 1.…”

Fixed‐wheel gates with wheels mounted on both sides that roll on roller path plates are used in both emergency intake gates and spillway gates in hydrogenerating stations. Environmental corrosion along with high wheel loads cause differences in the profile of the roller path surface. Combined with the relatively high torsional stiffness of the gate end girders, a condition of wheel load redistribution occurs where some wheels are relieved of load while others are loaded beyond their maximum design values. Failure of one wheel could jeopardize the overall operation of the gate. Furthermore, frequent operation of these gates result in changes in the stress profile in both wheels and roller paths that, potentially, could lead to failure. Currently, design guidelines for gate wheels and roller paths do not consider the fatigue life of these elements. Research‐based evidence is provided to support changes to these guidelines.

“…Rolling contact fatigue (RCF) is a typical failure mode in the application of gears. Surface damage is a very complex phenomenon and the contact fatigue plays a fundamental role in the damage process [1]. The fatigue damages are influenced by various factors, including the lubrication oil, surface roughness, and mechanical properties of materials [2][3][4][5].…”

17Cr2Ni2MoVNb steel is a new type of gear steel in the automotive industry; the rolling contact fatigue behavior is not well documented. In this study, some microscopic analysis methods (optical microscope (OM), scanning electron microscope (SEM), transmission electron microscope (TEM), X-ray diffractometer (XRD), and energy dispersive X-ray analysis (EDS)) were used to characterize material microstructure and damage surface. In addition, rolling contact fatigue behavior was evaluated by Weibull curve. The results show that the size of austenite grain increased while the quenching temperature increased. Moreover, the samples with a quenching temperature of 1000 °C exhibited the maximum mean life of 7.33 × 105 cycles. In addition, the failure mode of quenched at 900 °C and 1100 °C were delamination, and pitting was the main failure mode of 1000 °C.

A three-dimensional elastic-plastic finite element analysis (FEA) is carried out to estimate the rolling contact fatigue (RCF) crack initiation life for varied slip range on the rail arising from operational variations. The wheel load produces Hertzian contact pressure. Variation in engine traction induces slip variations that evolves thermal load in terms of heat flux. The aperiodic rolling of wheel on rail develops non-proportional multiaxial fatigue loading. Present study combines these effects by translating the wheel load on rail for multiple (twelve) pass in presence of thermal load, contact pressure and traction through a proposed simulation. The temperature dependent Chaboche material model with nonlinear kinematic hardening law is implemented to estimate the stresses and plastic strains governing the multiaxial fatigue condition at the interface. The location of maximum von Mises stress, found at a material point on or a layer below the rail-head, contemplates the fatigue crack initiation site. A coded search algorithm helps to identify the critical plane of crack initiation corresponding to the maximum fatigue parameter (FP). In contrast to available predictions of RCF life considering contact pressure and/or traction or frictional heat in isolation, present study combines all these loads together and provides a more realistic result by numerical simulation.
