摘　　要：介绍了液体动压轴承的工作原理,参照滑动轴承的设计流程完成液体动压轴承的设计,以计算流体力学为理论基础,以FLUENT软件为工具,着重研究了偏心率和主轴转速对油膜压力的影响,结果表明该轴承能够满足工作要求。In this paper, the working principle of fluid dynamic pressure bearing is introduced and it is designed referring to the design flow of sliding bearing. Based on the theory of computational fluid dynamics, by means of FLUENT software, the influence of eccentricity and spindle speed on oil film pressure is studied emphatically. The results show that the bearing can meet the working requirements.
