摘　　要：针对径向滑动轴承种类多,腔内压力油流动复杂,传统的基于理论编程的方法很难获得其精确模型的问题,采用ABAQUS/CFD软件建立了某径向滑动轴承计算流体动力学参数化仿真模型,分析得到了稳态下油膜压力与油膜流速的分布规律。结果表明,该型滑动轴承稳态特性符合设计要求;参数化的模型还可延用于后续大量的计算与分析,不仅为该系列滑动轴承的设计制造及试验分析提供了仿真依据,同时也开辟了一种新的高效经济的研究方法。In view of the variety of radial sliding bearing,the complex flow of pressure oil in the cavity, and the traditional theory based programming method is difficult to obtain the accurate model of the problem,using ABAQUS/CFD software to establish a radial sliding bearing calculation of fluid dynamics simulation model, analysis of the steady state oil film pressure and oil film flow velocity distribution law The results show that the steady - state characteristics of the sliding bearing are in accordance with the design requirements. The model can be used for the subsequent large number of calculation and analysis, not only for the design and manufacture of the sliding bearing of the series, but also provides a new research method of high efficiency.
