摘要/Abstract

摘要：

摘要：针对油膜轴承使用过程中巴氏合金ZChSnSb11-6衬套的蠕变损伤问题，设计了蠕变试验设备并对ZChSnSb116进行了蠕变试验.利用试验数据分别建立了基于Dom理论和恒速理论的2个稳态蠕变本构方程，通过试验验证了基于Dom理论的稳态蠕变本构方程的计算精度较高，其相对误差为1.52%;同时，基于ZChSnSb116的稳态蠕变本构方程建立了油膜轴承ZChSnSb11-6的蠕变寿命计算模型，以预测任意工况下轴承的使用寿命；测量了ZChSnSb116蠕变后的电阻率和硬度，分析了两者的关系并建立了基于电阻率的ZChSnSb11-6蠕变寿命评估模型，提出了一种通过测量合金电阻率评估轴承使用寿命的方法.

Abstract:

Abstract： Aimed at the creep damage problem of bushing Babbitt ZChSnSb11-6 of oil-film bearing in operation, the creep test equipment was designed, and a creep test of ZChSnSb11-6 was conducted. Two kinds of steady-state creep constitutive equations based on Dom theory and the constant speed theory were respectively established by using the creep test data. The experiment indicates that the steadystate creep constitutive equation based on Dom theory has a higher calculation accuracy, with a relative error of 1.52%. Besides, a creep life calculation model of ZChSnSb11-6 of oil-film bearing based on steady-state creep constitutive equation of ZChSnSb11-6 was established. The service life of alloy under any working condition could be predicted. Moreover, the resistivity and hardness of alloy after creep were measured, and their relationship was analyzed. Furthermore, the creep life evaluation model of ZChSnSb11-6 based on the resistivity was established, and a method measuring the resistivity of alloy to evaluate the service life of bearing was proposed.

Key words: oil-film bearing, Babbitt, creep test, creep life, evaluation
