| 概要 |
The influence of surface roughness on journal bearings is interesting to study because of its influence on improving their performance. This study examines the influence of introducing surface roughne...ss on the performance of bearings with the objective of improving lubrication, reducing cavitation, and minimizing noise. This research analyzes tribological features using a numerical approach in commercial CFD (computational fluid dynamics) software. Numerical results demonstrate that surface roughness improves bearing performance. These enhancements are notable in comparison to traditional journal bearings because they have a higher capacity to carry loads, a lower coefficient of friction, and produce less noise. On smooth journal bearings, the load carrying capacity, friction force, and average acoustic power level are 3171.34 N, 1123.6 N, and 80.6 dB, respectively. The roughness variation of Ra 12.5 on journal bearings results in 4650.5 N, 993.1 N, and 76.7 dB. Performance improved with a 46.6% increase in load capacity, an 11.6% reduction in friction, and a 4.8% decrease in noise, confirming the effectiveness of the proposed method.続きを見る
