The fluid-structure interaction (FSI) phenomenon has significant impact on the performance of aerostatic thrust bearings. To rapidly calculate their performance, this paper proposes a finite element method (FEM) based FSI modeling method. A FEM model of aerostatic bearing and a two dimensional FEM model of thrust plate were built, and the bidirectional data exchange between them was realized. Besides, the change of discharge coefficient caused by FSI phenomenon is considered by adopting a discharge coefficient model. The accuracy of the proposed FSI model is verified numerically and experimentally. The average calculation time is reduced from 9.36 h to 86.2 s for the case study. This research provides an efficient modeling method for the design of aerostatic thrust bearing considering FSI.
流固耦合（FSI）现象对静压推力轴承的性能具有显著影响。为快速计算其性能，本文提出一种基于有限元法（FEM）的FSI建模方法。建立了静压轴承的有限元模型和推力板的二维有限元模型，并实现了两者之间的双向数据交换。此外，通过采用流量系数模型，考虑了FSI现象引起的流量系数变化。所提出的FSI模型在数值和实验方面均得到验证。以案例研究为例，平均计算时间从9.36小时缩短至86.2秒。本研究为考虑流固耦合因素的静压推力轴承设计提供了一种高效的建模方法。 |
