为研究油膜轴承的结合性能，建立了油膜轴承轴瓦界面奇异应力场的数学模型和算法。采用有限差分法计算了油膜压力和油膜温度。计算并分析了不同条件下轴承端部界面奇异应力场的分布情况：巴氏合金层与钢基体结合时有无中间层，以及巴氏合金层与不同钢基体材料结合时。计算结果表明，含锡的界面产生了较高的应力奇异性，破坏了界面结合性能。在常用的基材中，40钢能有效地降低应力奇异性，因此，40钢相对更适合作为基材。根据GBT 12948-1991《滑动轴承双金属结合强度破坏性试验方法》建立了试件结合界面特征的力学模型，验证了温度对界面端奇异应力场的影响。
To explore the bonding performance of oil-film bearing, the mathematical model and algorithm on interface singular stress field of oil-film bearing bush was established. The oil-film pressure and oil-film temperature were calculated using finite difference method. The interface singular stress fields at the end of bearing under different conditions were calculated and analyzed: Babbitt alloy layer bonding to steel base with and without Tin as interlayer, and Babbitt alloy layer bonding to different steel base materials. The calculation results show that the interface with Tin generated higher stress singularity, which undermines the interface bonding performance. Among normal base materials, 40 steel could reduce the stress singularity effectively, therefore, it is relatively more suitable to be chosen as base material. Moreover, the mechanical model on bonding interface feature of test specimen was built according to GBT 12948-1991 Journal Bearing bi-metallic bonding strength destructive test method; the results validated the influence of temperature on singular stress field on interface end.
