摘　　要：文章针对水润滑条件下,利用雷诺方程,对稳定状态下赛龙径向轴承的流体动压润滑与等温弹流润滑进行数值模拟,讨论偏心率、载荷和转速对水润滑膜压力和厚度的影响。结果表明:偏心率对润滑水膜的压力与厚度影响明显,随着偏心率的增大,轴承润滑水膜的压力峰值不断增大,润滑水膜厚度的呈现减小趋势。转速对赛龙轴承润滑水膜压力的影响不明显,但是转速对润滑水膜厚度的影响比较明显,随着转速升高,润滑水膜厚度增大;载荷对赛龙轴承润滑水膜压力和厚度影响显著,随着载荷增大,水膜最大压力减小,膜厚也逐渐减小。In this paper,the numerical simulation of fluid dynamic pressure lubrication and isothermal elastohydrodynamic lubrication of Cylon radial bearings under steady state is carried out under the condition of water lubrication,and the influence of eccentricity,load and rotation speed on the pressure and thickness of water lubricating film is discussed.The results show that the eccentricity has a significant influence on the pressure and thickness of the lubricating water film.With the increase of the eccentricity,the pressure peak of the bearing lubricating water film increases continuously,and the thickness of the lubricating water film decreases.The effect of the rotational speed on the lubrication film pressure of the Cylon bearing is not obvious,but the effect of the rotational speed on the thickness of the lubricating water film is obvious.As the rotational speed increases,the thickness of the lubricating water film increases ;the load on the pressure and thickness of the lubricating water film of the Cylon bearing the effect is significant.As the load increases,the maximum pressure of the water film decreases and the film thickness gradually decreases.
