中文摘要：
通过轧机油膜试验台承载区运行温度测试以及油膜压力计算程序,得到承载区不同位置的温度与压力,并根据蠕变拉伸试验得到Graham方程的蠕变系数。基于ANSYS软件平台,模拟油膜轴承衬套巴氏合金在实际工作条件下的蠕变过程。模拟结果表明：油膜轴承衬套巴氏合金在实际工作条件下发生了蠕变,油膜压力对其蠕变有较大影响,在油膜压力较小区域温度对衬套巴氏合金的蠕变有一定影响;最大蠕变应力发生在油膜压力和温度最大的区域,且其随着半径的增加而逐渐减少。
英文摘要：
Temperature and pressure of different regions in load-carrying area and Graham creep coefficients were respectively obtained from creep tensile test of Babbitt alloy,test on lubricating performance of oil-film bearing oil and calculation program of oil-film pressure. Based on ANSYS software platform,creep process of oil-film bearing Babbitt alloy was simulated under the actual working condition. The results show that creep phenomena was occurred under the actual working condition,oil-film pressure played a major role in creep process of oil-film bearing Babbitt alloy,temperature had a certain influence on creep of oil-film bearing Babbitt alloy in the area of less oilfilm pressure,and the maximum creep stress was occurred in the area with maximum oil-film pressure and temperature,which decreased with the increase of radius.
