The journal bearing, a critical component of the rotating shaft, is influenced by various factors including friction, wear, and heat effects under actual working conditions. This study developed an advanced approach for optimizing the performance of journal bearings with surface texture. This approach allows for finding the influences of bearing parameters such as journal clearance, rotational speed, and shaft eccentricity ratio on the optimization results. The results show that whether under smaller journal clearances, higher rotational speeds, or larger shaft eccentricity ratios, the formation of intricate bifurcation patterns and enhanced branching in surface textures is consistently promoted. The optimized texture’s shape leads to a reduction in texture depth while significantly improving both the load-carrying capacity (LCC) and oil film thickness. This approach precisely determines the spatial and depth characteristics of texture elements, ensuring their optimal placement and geometry, and offers valuable insights and directions for future research.

With the deepening of the construction of 'Emerging Engineering Education', the traditional teaching of Mechanical Design course has exposed many shortcomings: one is the lack of practical engineering problems in the teaching process, which causes the disconnection between students' theory and practice, the other is the single teaching evaluation index, which makes it difficult to measure the comprehensive quality of students. Addressing these issues, the reform plan outlined in this paper emphasizes three core aspects: emphasizing the development of practical skills, fostering curriculum integration and interdisciplinary cooperation, and integrating ideological and political education into instruction. The objective of this plan is to comprehensively elevate the teaching quality and educational impact of Mechanical Design courses, thus aligning with the requirements for mechanical engineering professionals within the context of 'Emerging Engineering Education'.
