“…Generally, ceramic ball's rolling contact fatigue life is used to evaluate whether it can be used in rolling bearing, at present, as a new bearing ball fatigue life test rig: fatigue life test rig for ball with three point contact, it can not only test the traditional steel ball, but also ceramic ball [2] .The tested ball is forced by enlarged testing load by lever structure via driving roller, the driving roller has sunken arc, the tested ball is supported by the two escorting rollers, at the same time, the two escorting rollers are supported by guiding roller and supporting roller, thus, the test rig can work normally by external electromotor through the pulleys transmission, and rotating parts will produce eccentric mass due to uneven distribution of the quality, thus produce exciting force. The exciting frequency is equal to the rotating frequency [3] ; And sensor is on the cover of the testing rig, thus can obtain the output signal.…”

The exciting input signals of the parts in a fatigue life test rig for ball with three point contact and the system’s output signals were analyzed by auto-correlation and cross-correlation with MATLAB software, which eliminated the impact of noise to a certain extent and got the response signals of same frequencies caused by exciting input signals. Finally, the result showed that the text rig was linear by coherent function analysis, which provided the theory basis for modal and dynamic analysis further.

The application feedback on existing silicon nitride ceramic bearings and RCF experimental research all indicate that the primary failure mode of silicon nitride ceramic bearings is material spalling on the contact surface. Spalling failure occurs due to the initiation and propagation of cracks under rolling contact. However, silicon nitride ceramic bearings, owing to their unique manufacturing method, inevitably exhibit defects and cracks. Therefore, as silicon nitride ceramic bearings are increasingly prevalent, reducing the probability of spalling failure is crucial for extending their service life. This can only be achieved by gaining a clear understanding of the crack initiation and expansion mechanisms in silicon nitride ceramic bearings. This paper is based on silicon nitride rolling friction experiments. It involves the joint simulation of Franc3D-V8.4 and ABAQUS2020, wherein the crack front SIFs are calculated for each load contact position of the surface crack on the silicon nitride ceramic bearing ring during cyclic movement. The study also delves into the determination of the maximum effective stress intensity factors and explores the influence of the initial crack depth on the cycle life and direction of crack propagation. The research yields several valuable conclusions. The findings of this research offer theoretical guidance for formulating grinding technologies for silicon nitride rings and adjusting and controlling working parameters of silicon nitride ceramic ball bearings. These insights are crucial for enhancing the reliability and longevity of silicon nitride ceramic bearings in practical applications.

“…Many studies have addressed the issue of strength and ring crack initiation [2][3][4], crushing [5,6], and the tensile fracture of a notched ceramic ball [7] under quasi-static loading, as well as the rolling contact fatigue strength properties [8][9][10][11][12][13][14][15][16][17][18][19] at room and high temperatures. On the other hand, many studies have addressed the fracture behavior, fracture strength properties, and the evaluation of monolithic ceramics subjected to thermal shock [20][21][22][23][24][25].…”

The aim of this study was to clarify the fracture characteristics of ceramic balls, as used in bearings, when subjected to thermal shock. First, water-quench tests were performed on ceramic balls of a range of sizes. The fracture morphology and fracture surface were then observed. The crack propagation and branching behaviors were observed on the surfaces of the ceramic balls after they had been subjected to thermal shock. Manufacturing flaws were then observed on the surface of the fractures in the ruptured ceramic balls. Next, the relationship between the fracture strength, as calculated using a FEM analysis of the temperature difference at thermal shock fracture initiation and the equivalent crack length calculated from the manufacturing flaw size, was theoretically discussed to introduce a virtual crack model. As a result, it was concluded that the relationship can be estimated by applying a virtual crack model based on experimental data obtained from fracture strength tests for the difference fracture type, i.e., the temperature difference depends on the size of the manufacturing flaw. Finally, the temperature difference scatter was theoretically discussed based on the results of the two-parameter Weibull distribution in conjunction with a virtual crack model.
