Abstract

This work aims to study the effect of semi-ellipsoid texture on the bearing load capacity and maximum oil film temperature of tilting pad journal bearings. It has been shown that surface texture can improve the steady-state performance of bearings, but there are few studies on tilting pad journal bearings. A thermal elastohydrodynamic model of tilting pad journal bearings have been developed to support the analysis and solved by the finite difference method. The calculation results of the model are in good agreement with the simulation results of MADYN 2000 software, which proves the validity of the model. The effects of texture distribution, depth, radius, and density on the characteristics of tilting pad journal bearings were studied and compared with those of untextured tilting pad journal bearings. The results show that texture can significantly enhance or weaken the steady-state characteristics of tilting pad journal bearings, which is related to the texture parameters. This work provides a reference for the design of tilting pad journal bearings.

织构对可倾垫滑动轴承稳态特性影响的数值分析

本工作旨在研究半椭球织构对倾斜垫轴颈轴承承载能力和最大油膜温度的影响。已有研究表明，表面纹理可以改善轴承的稳态性能，但对可倾垫滑动轴承的研究很少。建立了可倾垫滑动轴承的热弹流动力学模型，并采用有限差分法进行了求解。模型的计算结果与MADYN 2000软件的仿真结果吻合较好，证明了模型的有效性。研究了纹理分布、深度、半径和密度对倾斜垫滑动轴承特性的影响，并与无纹理的倾斜垫滑动轴承进行了比较。结果表明，织构可以显著增强或减弱可倾垫滑动轴承的稳态特性，这与织构参数有关。该工作为可倾垫轴颈轴承的设计提供了参考。

期刊介绍： The Journal of Engineering Tribology publishes high-quality, peer-reviewed papers from academia and industry worldwide on the engineering science associated with tribology and its applications. "I am proud to say that I have been part of the tribology research community for almost 20 years. That community has always seemed to me to be highly active, progressive, and closely knit. The conferences are well attended and are characterised by a warmth and friendliness that transcends national boundaries. I see Part J as being an important part of that community, giving us an outlet to publish and promote our scholarly activities. I very much look forward to my term of office as editor of your Journal. I hope you will continue to submit papers, help out with reviewing, and most importantly to read and talk about the work you will find there."
