摘　　要：以实验室研制的高效磨床用液体静压轴承为例,利用流体动力学软件CFX对静压轴承的油膜进行稳态分析,得到油膜上的压力场;通过Workbench流固耦合分析模块对受油膜压力作用的静压轴承进行结构静力学分析,得到轴承的径向承载力和径向动态特性。研究结果可对静压轴承和磨床的转子动力学分析以及轴承的进一步设计与优化提供理论依据。In this paper,the hydrostatic bearing system used in high-efficiency grinding machine was taken as an example,the static pressure of bearing was analyzed by use of the fluid dynamics software CFX,and the pressure distribution of the hydrostatic bearing was obtained.Using the fluid-solid coupling analysis module in Workbench,the bearing capacity and the radial dynamic characteristic of the hydrostatic bearing were analyzed.The results may provide a theoretical basis for rotor dynamic analysis of hydrostatic bearing and grinding machine and the design and optimization of hydrostatic bearing.
