摘要

摘要: 利用有限单元法，数值分析轴向柱塞泵缝隙高度可变时阀门板上油膜的压力分布．缝隙中油压变化的确定，通常是应用Pasynkow润滑理论中的Reynolds方程．使用基于有限单元法的自编程序，数值地求解该方程．为了提高结果的精度，基于解的残差估计，应用了加密的自适应网格．给出了依赖于泵的几何条件和工作参数的计算结果．

Abstract: Numerical analysis of pressure distribution of oil film on the valve plate in variable height gap of an axial piston pump is concerned. The analysis employs the finite element method. For determination of oil pressure variations in the gap the Reynolds equation, commonly applied in the theory of lubrication by Pasynkov, was applied. The equation was solved numerically with the use of self-developed program based on finite element method. In order to obtain high accuracy of the results an adaptive mesh refinement based on residual estimations of solution errors was applied. The calculation results were represented as dependent on the geometric and working parameters of the pump.
