| 中文摘要: |
| 基于有限宽轴承理论，采用有限差分法运用MATLAB求解二维Reynolds方程，求解滑动轴承油膜压力分布，然后求解油膜承载力、偏位角等，同时研究得到宽径比、偏心率对油膜承载力、偏位角变化规律的影响。最后给出具体算例求解某防爆电机用滑动轴承的相关特性参数，应用Fluent软件对算例轴承模型进行流场分析。 |
| 英文摘要: |
| Oil film pressure distribution on the hydrodynamical sliding bearing was calculated by solving the Reynolds equation by Matlab based on finite journal bearing theory and finite differential equation .Influence of width-diameter ratio and eccentricity on oil film support capacity and attitude angle was further researched by solving eccentricity on oil film support capacity and attitude angle. Finally, an example of explosion-proof electric sliding bearing as well as a flow field analysis of bearing model wear given to solve the characteristic parameters. |
