“…Researchers have found a deviation of approximately 10% between the maximum wear depth calculated by Abaqus and the actual measurement results. Subsequently, Luo et al [12] proposed the concept of wear step size in further research to improve the wear model of self-lubricating joint bearings, and corrected the distortion of the internal mesh of the model by introducing wear step size. By calculating the improved model, it was found that the wear in the middle area of the joint bearing was the highest, while the wear in the boundary area gradually decreased, with a relative error of about 6.38%.…”

Spherical friction pairs are widely used in mechanical equipment, and predicting the wear of spherical friction pairs can help evaluate and predict bearing life. At present, when using the finite element analysis method to calculate the wear of spherical friction pairs, it is still necessary to simulate under idealized conditions, and the limitations of calculation amount and time need to be considered. The accuracy of the prediction method is measured by experimental means to measure the wear amount, which can be characterized by measuring the mass, volume, or wear thickness of the material under grinding. Based on the wear test methods used and the characteristics of the tested materials, suitable wear characterization parameters and measurement methods can be selected. This article also analyzes the influence of friction pair materials and service conditions on the wear of spherical friction pairs. Finally, the article looks forward to the development trend of predicting the wear of spherical friction pairs.

“…Contact analysis models were established using the finite element method (FEM) to calculate contact pressure, and the results were used to modify design parameters until all requirements were met. Luo [23,24] introduced methods for estimating the static load rating of spherical plain bearings and conducted life tests on new joint bearings using a testing machine. Spherical bearings have also found application in ship engineering [23][24][25][26][27][28][29][30].…”

This paper presents a theoretical model for calculating the carrying capacity of spherical hydrostatic bearings, including the deduction and solution of differential equations for fluid flow in the oil seal and the generation of bearing characteristic parameters. An example is used to verify the accuracy of the proposed calculation model. Additionally, the influence of dynamic pressure on the bearing capacity is investigated under various speed conditions. The results demonstrate that as the minimum width of the oil gap decreases, the maximum dynamic pressure increases non-linearly. Furthermore, the maximum dynamic pressure increases with higher rotational speeds, particularly when the width is smaller.

To calculate the carrying capacity of spherical hydrostatic bearings, a numerical calculation model was presented. The influence law of dynamic pressure effect on the carrying characteristics of liquid hydrostatic spherical bearings is revealed. Under general working conditions, the dynamic pressure effect caused by the radial eccentricity of the bearing has little influence on the bearing load characteristics parameters; when the minimum width of the gap between the sealing edge is very small and the bearing rotational speed is high, the dynamic pressure effect is more obvious.
