“…Noteworthy, many studies have verified that FIV is easy to be triggered at a larger COF, and the intensity and tendency of FIV will become stronger with the increase of the COF [21,22]. However, in this study, although the COF of SPTS is relatively large, no visible FIV phenomenon is observed.…”

Three kinds of laser surface texture (LST), i.e. square pit-textured surface (SPTS), round pittextured surface (RPTS) and groove-textured surface (GTS), are fabricated on the flat brass (H65) sample surfaces. The current-carrying tribological behaviour of these surfaces are investigated. It is noticed the COFs of smooth surface, SPTS and RPTS are all greater than 0.6 after the test, while the GTS has the lowest COF, which remains around 0.2 throughout the test. The vibration signals detected from all surfaces indicate the larger COF will not trigger the FIV generation in this state. All the texture surfaces will not cause electrical contact breaks. Worn surface analysis indicates the wear level of GTS is the weakest, with slight damage and debris accumulation occurs along the groove edges. Finite element analysis is performed to calculate the variation of contact force, contact temperature and voltage signal, and the test results can be well explained.

“…Tu [15,16], considering sliding and modifying the deformation coefficient of non-ideal Hertz contact, proposed vibration response dynamic models for cylindrical roller bearings. Xu [17], using a mixed lubrication model, explored the frictional vibration mechanism under rough sliding-rolling contact. Most of the above models did not describe the impact of fault excitation on the model or simplified the fault excitation into a single-pulse process.…”

Fault mechanism analysis is one of the methods in fault diagnosis, and the dynamic modeling of rolling bearing faults plays a crucial role in studying fault mechanisms. Existing dynamic fault models only consider the impact of fault size and bearing speed on the impact force, providing an incomplete description of the impact force. In order to more accurately describe the dynamic fault model of impact forces, this paper focuses on the deep groove ball bearing with outer race faults. Factors such as defect deformation, speed, and fault size are considered, and an instantaneous impact force excitation function is proposed. Based on this proposed excitation function, a dynamic model for the outer race fault of deep groove ball bearings is established. Finally, through simulation and experimental comparison, the results indicate that the fault characteristic frequencies and their harmonics of the model in this paper are closer to the actual fault characteristic frequencies, reducing the error by 1 to 2 Hz. Therefore, the model proposed in this paper is more effective and accurate, providing a more precise rolling bearing fault model for the study of fault mechanisms.

“…For large-sized and heavy rolling elements, even if the axial load is large enough, the macro-slip disappears and the gyro-slip still exists. At this time, the self-rotation angle of the Although the phenomenon of over-skidding is rarely involved, the skidding of rolling bearings and its related dynamic behavior [6][7][8][9][10][11][12][13] have been experimentally and theoretically studied. A vibration signal-based method for predicting faulty rolling bearing skidding rate and enhancing fault features has been proposed [7,8], and the bearing performance degradation is evaluated accordingly.…”

“…[20] can be targeted to the skidding ratio analysis of a specific rolling element. Liu [21] and Tu [6] conducted research on the cylindrical roller bearing vibration responses as skidding occurs, and discussed the effects of frictional force [11,13] and cage pocket type. The results indicate that a proper cage pocket size (tilt angles of 5° and 10° for the front and rear walls can attenuate the skidding degree, and the skidding-induced friction forces are www.Springer.com/journal/40544 | Friction strongly related to the vibration level.…”

Dynamic, thermal, and vibrational analysis of ball bearings with over-skidding behavior

et al. 2022

The term “over-skidding” indicates that the cage rotational speed ratio exceeds the theoretical value as ball purely rolls on the raceway. Different from the skidding phenomenon that occurs in low-load and high-speed bearing, over-skidding usually occurs in large-size angular contact bearings, and it is still difficult to suppress under high load conditions. The main forms of damage to the raceway by over-skidding are spinning and gyro slip. To further explore the vibration characteristics and thermal effects of this phenomenon, a set of over-skidding tests of an angular contact bearing with a bore diameter of 220 mm were conducted on an industrial-size test bench. Through the experiment, the influence of axial load, rotational speed, and lubrication conditions on the occurrence of over-skidding were determined. Based on a previous dynamics model, the heat generation and thermal network models were integrated in the present study to predict the over-skidding and its thermal behavior. The model was validated in terms of the measured degree of over-skidding and temperature rise. The results showed that the degree of over-skidding reaches up to 12% of the theoretical value, and the friction power loss of the ball-pocket accounts for 30% of the total power loss. The analysis of the vibration signal showed a strong correlation between the bearing vibration characteristics and over-skidding behavior, thereby providing a way to indirectly measure the degree of over-skidding.
