摘    要:通过建立轴向柱塞泵配流副的几何模型,利用雷诺方程推导了配流副的油膜压力方程,采用有限差分法和松弛迭代法求解雷诺方程。利用FORTRAN语言编程求解,利用MATLAB语言对油膜厚度、压力、温度分布进行了仿真研究。结合油膜厚度方程、雷诺方程、能量方程、弹性变形方程、黏温黏压方程和密度温压方程,仿真微观织构配流副的热弹流润滑特性。研究表明:配流副油膜厚度增大,最大油膜压力减小,最高温度值减小;配流副的热-流-固耦合效果随油膜间隙收敛逐渐明显,在最小油膜厚度处达到最大,并且,油膜压力值达到最大;加工微观织构可以显著改变配流副的油膜压力和温度分布。

关 键 词:配流副  雷诺方程  热-流-固耦合  微观织构

Abstract:The geometric model of the port plate pair of the axial piston pump is established. The oil film pressure equation of the port plate pair are deduced by Reynolds equation. The Reynolds equation is solved by finite difference method and relaxation iteration method. The Reynolds equation is solved by FORTRAN language programming. The oil film thickness and pressure distribution are simulated by MATLAB language. The Thermo-Elastohydrodynamic lubrication characteristics of micro-texture port plate pair are calculated by combining the oil film thickness equation, Reynolds equation, energy equation, elastic deformation equation, viscous-temperature-viscous-pressure equation and dense-temperature-pressure equation. The oil film thickness of the port plate pair increases, while the maximum oil film pressure decreases, and the maximum temperature increases. The thermal-fluid-solid coupling effect of the port plate pair gradually converges with the oil film gap, and reaches the maximum at the minimum oil film thickness, where the oil film pressure reaches the maximum value. Machining micro-texture can significantly change the oil film pressure and temperature distribution of the port plate pair.
Keywords:   port plate pair  reynolds equation  thermal-fluid-solid coupling  micro-texture
