| Abstract (English): |
The wear behavior of the inner lining material of water-lubricated bearings under low-speed heavy-load conditions is highly complex and has a direct impact on equipment reliability and lifespan. To investigate the wear characteristics of water-lubricated bearings under such conditions, the Archard wear model was employed as the theoretical foundation, and the finite element analysis software ABAQUS was used for simulation modeling. A specialized Umeshmotion subroutine was developed in conjunction with ALE adaptive meshing technology to achieve dynamic simulation of the bearing wear process. To validate the effectiveness of the proposed method, a series of rigorous experimental tests were designed and implemented. The results show that this method not only calculates wear displacement in real-time but also accurately captures changes in stress-strain distribution during the material removal process, which significantly enhances the realism and predictive capability of the simulation. By comparing the measured wear volumes from actual bearings under identical operating conditions, it is found that there is a high degree of consistency between the simulation and experimental data, with an average error of only 4. 26%. This confirms the reliability and accuracy of the method in predicting the wear behavior of waterlubricated bearings. Furthermore, by adjusting parameters within the subroutine, the proposed method can provide precise predictions of bearing wear scenarios under other specific conditions encountered in practical engineering applications, thus offering a reliable numerical calculation tool for forecasting bearing wear.
