Abstract
The tribological behavior and transient respones of a round and stepped recess sliding bearing used in high-speed spindles was studied. A transient analysis method based on computational fluid dynamics and fluid-structure interaction was presented. Phase changing condition based on pressure was adopted to analyze the cavitations of lubricating fluid. An experimental bearing system of a lubrication velocity field visualization and another in the literature were analyzed. The correctness of the transient coupled analysis was verified. After analyzing the round and stepped recess bearing system in the transient process from a static start to stable operation, the influence law of load form and size, speed, inlet pressure on bearing system lubrication characteristics and journal trajectory were obtained.
