摘　　要：分析了点、线支承推力轴瓦的机械变形,进行了有限元数值模拟。结果表明:同一轴瓦、相同工况条件下,点支承的挠变形最大,挠变形主要是径向弯曲变形,周向挠变形较小,且随着轴瓦长/宽比的减小而愈加明显。线支承的挠变形主要是周向弯曲变形,且沿周向左右对称,径向挠变形较小,挠变形与支承长度和宽度有关,随其增大而变小。Finite element numerical simulation is carried out to analyze mechanical deformation of thrust bearing under the point and line supporting condition. The simulation results indicate that the torsion deformation of the point supporting is the larger, torsion deformation is mainly radial bending deformation, and circumferential bending deformation is small, it becomes more and more obvious with the decrease of bearing pad length-width ratio under the same working conditions for the same pad. Line supporting torsion deformation is mainly the circumferential bending deformation, and the left and right sides are symmetrical along the circumferential, the radial bending deformation is small, torsion deformation relates to the length and width of supporting, the torsion deformation decreases with the size increase of length and width of supporting.
