    摘要:

    水润滑轴承大多采用非金属材料作为轴瓦材料,此类材料的弹性模量较小,所以在承受载荷时,轴瓦易产生弹性变形,因此研究弹性变形对水润滑轴承承载性能的影响极为重要;利用ANSYS有限元软件的流固耦合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相对比,具体分析了在不同偏心率、转速条件下,轴瓦弹性变形对轴承承载力的影响范围;通过计算以及对比分析的得到的结果,不但为水润滑轴承承载性能的研究提供了技术参考,而且为水润滑轴承轴瓦材料的选择与水润滑轴承的结构设计提供了依据。

    Abstract:

    Because bearing bush material of water-lubricated bearings generally adopts non-metallic materials with low elastic modulus, the bearing bush is prone to produce elastic deformation when under load. Therefore, it is very important to analyze the bearing performance of water-lubricated bearings when deformation happens. The bearing capacity of water-lubricated bearings with elastic deformation is calculated by fluid-structure coupling method of ANSYS finite element software, and compared to the case without elastic deformation. The influence ranges of bearing elastic deformation on bearing capacity under different eccentricities and speeds are specific analyzed. The results obtained through calculation and comparative analysis are not only technical references for the study of bearing performance of water-lubricated bearings, but also bases for the selection of bearing bush materials and structural design of water-lubricated bearings.
