轴瓦弹性变形对水润滑轴承承载性能的影响

利用ANSYS有限元软件的流固耦合（Fluid-Structure Interaction，FSI）方法对计入弹性变性后水润滑轴承的承载力进行计算，并且与不计入弹性变形时的情况进行对比，具体分析在不同偏心率和转速条件下轴瓦弹性变形对轴承承载力的影响范围。在轴瓦材料弹性模量优先取值为1 000 MPa的情况下，当转速超过1 000 r/min、偏心率≥0.8时，弹性变形对轴承承载力的影响急剧增大。通过计算和对比分析得到的结果不仅为水润滑轴承承载性能的研究提供技术参考，而且为水润滑轴承轴瓦材料的选择和水润滑轴承的结构设计提供依据。

Influence of Bearing Bush Elastic Deformation on Bearing Performance of Water-Lubricated Bearings

The bearing capacity of water-lubricated bearings with bearing bush elastic deformation is calculated by fluid-structure interaction (FSI) of ANSYS finite element software and compared to the case without elastic deformation. The influence ranges of bearing bush elastic deformation on bearing capacity under different eccentricities and speeds are specifically analyzed. Under the condition of the preferred modulus value of bearing bush material is 1 000 MPa, the influence of elastic deformation on bearing capacity increases sharply when the rotational speed exceeds 1 000 r/min and eccentricity is greater than or equal to 0.8. The results obtained through calculation and comparative analysis are not only the technical references for the study of bearing performance of water-lubricated bearings, but also the bases for the selection of bearing bush materials and structural design of water-lubricated bearings.
