摘要

在轴颈轴承建模中,气蚀现象对于提高模拟结果的准确性非常重要。这是因为,由于存在收敛和发散几何形状,气蚀几乎肯定会发生。模拟结果将接近真实情况,从而对研究人员设计最佳轴颈轴承产生积极影响。无气蚀和有气蚀建模对轴颈轴承建模的影响对轴颈轴承的润滑性能有很大影响。在有气蚀的建模中,轴颈轴承所能依靠的最大流体动力压力和承载能力会有相当快的增长。建模结果还与发生在轴颈轴承中的摩擦力有关。本研究的目的是探讨加入流体动力压力建模的效果。使用基于软件的有限体积法对有气蚀和无气蚀的结果进行比较。这里采用的是混合多相气蚀。数值结果表明,无气蚀和有气蚀的轴颈轴承模型对轴颈轴承的润滑性能有很大影响。在有气蚀的建模中,轴颈轴承所能依靠的最大流体动力压力和载荷承载能力会有相当快的增长。建模结果还与发生在轴颈轴承中的摩擦力有关。

A Comparative Study on Hydrodynamic Analysis with and without Cavitation Modelling: A Study on Textured Slip Journal Bearing
In journal bearing modeling, the phenomenon of cavitation is very important to improve the accuracy of the simulation results. This is because cavitation will almost certainly occur because there are convergent and divergent geometries. The results of the simulation will be close to real conditions so that it can have a positive effect on researchers in order to design optimal journal bearings. The effect of modeling without cavitation and with cavitation on journal bearing modeling has a great influence on the lubrication performance of journal bearings. In modeling with cavitation, the maximum hydrodynamic pressure and load carrying capacity that the journal bearing is capable of relying on has a fairly rapid increase. The modeling results also relate to the friction force that occurs in the journal bearing. The aim of the present study is to explore the effect of inclusion of modeling of the Hydrodynamic pressure. The finite volume method based on software is used to compare the result with and without cavitation. Here, The mixture multiphase cavitation is adopted. The numerical result show t he effect of modelling without cavitation and with cavitation on journal bearing modelling has a great influence on the lubrication performance of journal bearings. In modelling with cavitation, the maximum hydrodynamic pressure and load cmarrying capacity that the journal bearing is capable of relying on has a fairly rapid increase. The modelling results also relate to the friction force that occurs in the journal bearing.
