摘要
介绍了液体静压导轨支承的设计,并对其油膜压力分布进行了研究。根据流体润滑理论及雷诺方程,构建了导轨油膜压力的数学物理模型,提出了运用有限元法进行油膜刚度及导轨承载能力的分析与计算方法。借助非线性有限元软件M arc对一个应用实例进行了分析与计算,得到油膜压力的分布云图和曲线,求解出了油膜刚度和导轨的承载能力。计算结果表明,该方法计算结果精确,可以满足设计要求。
The design of hydrostatic slider was introduced. The pressure distribution of oil film in a hydrostatic slider was investigated. The mathematical equations of oil film pressure were deduced according to the hydro-lubrication theory and Reynolds equations. The analysis and calculating methods of the stiffness and the load capacity of oil film were presented by adopting the methods of finite element analysis （FEA）. A practical sample was simulated with Marc. The contour band, curves of the pressure distribution with the load capacity and the stiffness of oil film were achieved. The numerical results indicate that it is accurate enough to meet the demand of the design.
