“…These properties are all modeled by fatigue. There have been many outstanding researches, [22][23][24][25][26][27][28][29] in which those of Bhatti and Wahab 30,31 always changed parameters in assessing deterioration of fatigue bearing structures. These researches exploited different properties of structures under impact of (cyclic or non-cyclic) forces to determine the relation between assessment parameters with deterioration.…”

We present a novel approach to evaluating mechanical features of structures using correlation coefficients and fast Fourier transform analysis. Although correlation coefficient is always a sensitive parameter to changes of mechanical properties of real structures, it is rarely used due to high complication in data collection. To overcome this drawback, we propose fast Fourier transform analysis to increase the sensitivity of correlation coefficient, simplify calculation, and retain information from the original signal. Numerical results show that the present method not only detects relation between changes in structure with progression of defects but also locates their position. An fast Fourier transform–based correlation coefficient approach provides evaluations in both real bridge structures and experimental models. This study can serve as reference for analyzing, evaluating, and identifying working status of real structures.

“…Their results showed that under interference condition, the crack growth was much faster than that of in‐plain fatigue condition. Lee et al . characterised the fretting damage of press‐fitted shaft below the fretting fatigue limit based on a small‐scale shaft with a diameter of 16 mm, and the diameter of the hub was 40 mm with contact length of 30 mm.…”

“…The propagation property of fatigue crack in shrink-fitted shaft has been studied by Alfredsson et al 8 Their results showed that under interference condition, the crack growth was much faster than that of in-plain fatigue condition. Lee et al 9 characterised the fretting damage of press-fitted shaft below the fretting fatigue limit based on a small-scale shaft with a diameter of 16 mm, and the diameter of the hub was 40 mm with contact length of 30 mm. Even below the fretting fatigue limit, multiple fretting fatigue cracks still emerged in the contact edge.…”

Fretting damage failure analysis of a Chinese carbon railway axle RD2 was carried out. The wheel hub was in situ cut to expose the damaged surface of the wheel seat to avoid additional damage. A small‐scale axle test rig was developed, and simulation tests were performed at different rotator speeds of 1800 and 2100 rpm. The wear mechanism of fretting damage areas was a combination of abrasive wear, oxidative wear and delamination. The fracture surfaces exhibited characterization of multisource and step‐profile. The fretting fatigue crack initiated at the subsurface and propagated along an inclined angle at the first stage. The fretting damage at the higher speed was more severe compared with the lower speed, which lead to a relatively shorter fatigue life. The damage morphologies of the axle in the simulation tests were in good agreement with that observed in the failure analysis on real axle.

“…Full scale test rigs are also used to test connection techniques that are frequently used but still give problems, like press-fitted connections [8][9][10][11]. This connection technique is frequently used to connect a shaft with a bearing, a gear, a flywheel, etc.…”

There is no standard or generally accepted test rig for fretting fatigue experiments. Therefore,researchers adopt an existing concept, or build a new test rig that meets their specific requirements.However, too many different test rigs may be disadvantageous because the results of two different test rigsare hard to compare. The increasing amount of diversity is mainly caused by the lack of a recent literaturesurvey on fretting fatigue test rigs. In 1994, Hills and Nowell described a few test rigs in Mechanics OfFretting Fatigue. In this study, the authors made a classification of test rigs based on the contact geometry,which is determined by the test specimens, not by the test rig itself.Ghent University, Laboratory Soete, BelgiumThe authors of this article present a review of the available literature, and present a classification based onthe properties of test rigs. Fretting fatigue test rigs are first divided in two categories based on the geometryof the test specimen: full scale and coupon scale test rigs. The latter are mostly used to perform researchand are subdivided in categories based on increasing functionalities. This is the ability to apply a fatigueload, a constant normal force, and an alternating slip in the range of some micrometers. In time, from thefifties until now, progress has been seen in the design of fretting fatigue test rigs. More parameters can becontrolled during experiments and more measuring techniques are incorporated. State of the art test rigsare classified in the last category with most functionalities, but still have imperfections. Future designerscan use this article to classify their needs, or help to design a better test rig knowing the imperfections ofthe state of the art test rigs.
