| 摘 要： | 应用边界单元法（ＢＥＭ），对平面应变情况下滑动轴承无摩擦接触时的接触参数进行了分析计算，并与常规Ｈｅｒｔｚ公式计算结果进行了对比。结果表明，用边界单元法可以提高接触参数的计算精度，并妥善解决了Ｈｅｒｔｚ公式计算值偏低的问题。另外在分析了轴承系统尺寸、材料参数及载荷变化因素而进行相应计算的基础上，给出了滑动轴承接触参数计算的经验公式。

| Abstract: | The contact parameters of journal bearing without friction under plane strain conditions were calculated by using boundary element method. The result was compared with that of classicai Hertzian theory. The calculation precision was improved by using the boundary element method, and the problem about lower value from Hertz formula was solved. The experiential calculation formulas were obtained with consideration of some parameters for the journal bearing. |
