Abstract

Purpose

The present paper aims to analyse the synergistic effect of pocket orientation and piezo-viscous-polar (PVP) lubrication on the performance of multi-recessed hybrid journal bearing (MHJB) system.

Design/methodology/approach

To simulate the behaviour of PVP lubricant in clearance space of the MHJB system, the modified form of Reynolds equation is numerically solved by using finite element method. Galerkin’s method is used to obtain the weak form of the governing equation. The system equation is solved by Gauss–Seidal iterative method to compute the unknown values of nodal oil film pressure. Subsequently, performance characteristics of bearing system are computed.

Findings

The simulated results reveal that the location of pressurised lubricant inlets significantly affects the oil film pressure distribution and may cause a significant effect on the characteristics of bearing system. Further, the use of PVP lubricant may significantly enhances the performance of the bearing system, namely.

Originality/value

The present work examines the influence of pocket orientation with respect to loading direction on the characteristics of PVP fluid lubricated MHJB system and provides vital information regarding the design of journal bearing system.

带压粘式极性润滑剂的四袋混合轴颈轴承的袋口方向影响

设计/方法/途径为了模拟 PVP 润滑剂在 MHJB 系统间隙空间中的行为，使用有限元法对雷诺方程的修正形式进行了数值求解。伽勒金方法用于获得支配方程的弱形式。系统方程采用高斯-潮汐迭代法求解，以计算节点油膜压力的未知值。模拟结果表明，加压润滑剂入口的位置会显著影响油膜压力分布，并可能对轴承系统的特性产生重大影响。此外，使用 PVP 润滑剂可显著提高轴承系统的性能。原创性/价值本研究探讨了相对于加载方向的轴承座方向对 PVP 流体润滑的 MHJB 系统特性的影响，并提供了有关轴颈轴承系统设计的重要信息。同行评议本文的同行评议记录可在以下网址查阅：https://publons.com/publon/10.1108/ILT-07-2023-0241/。
