“…However, it is quite time-consuming when estimating the damage accumulation of each loading cycle because of the high-cycle fatigue characteristics of the gears. Hence a method called "jump-in-cycles" reported in Reference [128] was applied for both the calculation accuracy and efficiency. Based on this method, the gear surface roughness could be assumed to remain unchanged over a finite loading block ∆N.…”

With the mounting application of carburized or case-hardening gears and higher requirements of heavy-load, high-speed in mechanical systems such as wind turbines, helicopters, ships, etc., contact fatigue issues of gears are becoming more preponderant. Recently, significant improvements have been made on the gear manufacturing process to control subsurface-initiated failures, hence, gear surface-initiated damages, such as micropitting, should be given more attention. The diversity of the influence factors, including gear materials, surface topographies, lubrication properties, working conditions, etc., are necessary to be taken into account when analyzing gear micropitting behaviors. Although remarkable developments in micropitting studies have been achieved recently by many researchers and engineers on both theoretical and experimental fields, large amounts of investigations are yet to be further launched to thoroughly understand the micropitting mechanism. This work reviews recent relevant studies on the micropitting of steel gears, especially the competitive phenomenon that occurs among several contact fatigue failure modes when considering gear tooth surface wear evolution. Meanwhile, the corresponding recent research results about gear micropitting issues obtained by the authors are also displayed for more detailed explanations.

“…Due the importance of this matter, many papers seek to understand the mechanism of this problem. However, the study of contact between bearing parts is known to be a complex issue, since the contact area is subjected to stresses as high as 2∼5 GPa (Norton, 2013;Rycerz, Olver, and Kadiric, 2017;Morales-Espejel and Gabelli, 2015;Bhattacharyya, Londhe, Arakere, and Subhash, 2017;Li, Hu, Meng, Zhan, andShen, 2017 Arakere, 2016), as well as several other parameters that have an impact on the situation, such as lubrication, vibration, roughness (Yusof and Ripin, 2014), bearing dimensions (Chen and Wen, 2015), rotation speed, applied loads (Guo, Cao, He, and Yang, 2015), and the curvature of the inner and outer rings (Deng, Hua, Han, and Huang, 2013;Chen and Wen, 2015). Therefore, each parameter must be examined thoroughly, seeking to determine the influence of its behavior on RCF.…”

“…RCF has a different behavior in each type of bearing, due to the difference in their contact geometry. Morales-Espejel (2014) and Deng et al (2014) discussed the phenomenon in roller bearings, whereas Li et al (2017) examined the performance of tapered roller bearings, and Lostado, Martinez, and Donald (2015) studied self-aligning roller bearings. This paper proposes a simplified model for a deep-groove ball bearing.…”

Bearings are mechanical elements capable of transferring motion between two or more parts in a machine. When an external load is applied, the rolling elements and their rings tend to initiate a cyclical movement between themselves. Hence, they are linked by a variable type of contact, thus creating high surface stresses. As these elements are subjected to millions of cycles within their lifespan, these cyclical stresses may create cracks and cause failure by rolling contact fatigue (RCF). Due to the importance of this subject, it is vital to study the stress field caused by contact between the rolling parts in a bearing. This paper offers two approaches on the cyclical stresses in a deep-groove ball bearing: an analytical approach, using Hertz’s theory for contact stresses; and a numerical simulation, using the Finite Element Method (FEM) with the software Inventor and Nastran In-CAD. The results of both approaches were compared, and stress behavior was analyzed as the depth of the inner ring was increased. It was concluded that the surface stresses are greatly superior than the strength of the materials used in the bearings, and that the area influenced by these stresses are small when compared to the dimensions of the whole.

“…Many researchers also focused on the anisotropy nature of damage (Badreddine et al., 2015; Nasab and Mashayekhi, 2019). After decades of development, CDM had been used for the simulations of creep (Christopher and Choudhary, 2019; Liu et al., 2020), fatigue (Liu and Yan, 2019; Zhu et al., 2019), creep–fatigue interaction (Guo et al., 2020; Wang et al., 2020), brittle damage (Guo and Kuang, 2019; Li et al., 2019), and ductile damage (Nasab and Mashayekhi, 2019) and had been successfully applied to the damage analysis of engineering structures (Guo et al., 2020; Li et al., 2017; Shen et al., 2016, 2017; Wang et al., 2019; Zhang et al., 2019). For example, Li et al.…”

A new damage-coupled cyclic plastic model for whole-life ratchetting of heat-treated U75V steel

In the framework of continuum damage mechanics, a new damage-coupled cyclic plastic model is proposed to describe the nonlinear evolution of whole-life ratchetting and its dependence on the stress level. The characteristic that the damage evolution rate of U75V heat-treated steel decays in the initial load cycles is considered by introducing a modified term into classic damage evolution equation. A hybrid fatigue failure criterion considering both the fatigue and ratchetting strain-induced failures is established based on the fatigue failure rule concluded from experiments. Comparisons between simulated and experimental stress–strain hysteresis loops, ratchetting strains, damage evolutions, and fatigue lives are performed to validate the proposed model.
