【摘要】 对三峡右岸小支柱簇双层瓦推力轴承进行了热弹性流体动力润滑性能有限元分析。采用推力轴承润滑计算的有限元程序,并借助ANSYS软件的热传导和热弹变形分析功能,形成了一套完整的推力轴承热弹流动力润滑性能分析软件。物理模型包括润滑油膜、推力轴承和镜板推力头。对三峡试验推力轴承性能的计算结果和测量结果进行了对比分析,计算结果和实测的结果吻合,优化设计了三峡右岸推力轴承。更多还原

【Abstract】 The thermo-elastic-hydrodynamic lubrication performance of three gorges thrust bearing(right) with pins and double layer system have bean analyzed by the finite element methods.The lubrication calculation is programmed with the finite element methods.Together with ANSYS soft,a complete software of the thermo-elastic-hydrodynamic(TEHD) lubrication performance analysis is obtained in this paper,where the physical model includes lubricating oil film,thrust bearing,runner and thrust head.The thermo-elastic-deformation of thrust bearing and runner is analyzed with ANSYS.The calculated results are compared with the measured ones in real operation.It shows that calculated characteristics are coincident with the experimental measurement.Three Gorges thrust bearing(right) have bean optimized.更多还原
