摘　　要：以具有深浅腔的动静压轴承为研究对象,基于Gambit对油膜进行网格划分并建立三维有限元模型,通过FLUENT仿真得到不同偏心率和转速下轴承的油膜三维压力场分布和静特性参数。计算结果表明:深浅腔动静压轴承在每个浅腔处油膜出现压力峰值,且承载力随偏心率和转速的增加而增加。该仿真方法计算结果与文献数值计算结果相吻合,为进一步研究动静压轴承的其他性能提供了一种新的方法。The static characteristic parameters and the oil film tricity ratio and different rotational speed were obtained bearing pressure field distribution under different eccen- through the three-dimensional finite element modeling by Gambit and FLUENT simulation. FLUENT simulation results illuminate that oil film pressure peak of the deep/shallow pockets hy- brid bearing appears in the every shallow pocket, and the carrying capacity is increased with the increase of eccentricity ra- tio and rotational speed. The simulation results of this method are close to the numerical calculation results of references, it provides a new method for the further study of the hybrid bearing performance.
