|
摘要
以水压三用阀阀芯为研究对象,通过在阀芯表面加工微造型以改善其润滑和抗磨性能。采用CFD方法建立阀芯微造型的动压润滑模型,研究阀芯表面的压力分布和承载力特性,然后选择L_(27)(3~5)交互试验表,开展动压承载力的交互试验分析,研究分析液膜厚度、微造型深度、半径、形貌、阀芯移动速度以及液膜厚度与微造型深度、半径之间的交互作用对阀芯承载力的影响,并确定最优模型。结果表明:在阀芯表面设置微造型能够在阀芯与阀套之间产生承载力,各因素中对液膜承载力的影响由强至弱依次是液膜厚度、阀芯移动速度、微造型半径、形貌以及深度,最终分析得到的最优模型A_3B_3C_3D_1E_3,比方案中的最大承载力提高了14.5%。
Taking a three function valve core of water hydraulic as the research object, we improve its lubricating and anti-wear performance by texturing on surface of the valve core. The CFD method is used to establish a dynamic pressure lubrication model of valve core texturing, and to analyze pressure distribution and bearing force of valve core surface, and then we select the L_(27)(3~5) interaction test table to study liquid film thickness, texturing depth, radius, shape, valve core speed and the interaction between liquid film thickness and texturing depth and radius on bearing force performance of valve core and determine the optimal model. The results show that the bearing force between the valve core and the valve pocket can be produced by micro-modeling of valve core surface. The influence of various factors on bearing force performance of valve core from strong to weak is liquid film thickness, valve core movement speed, micro molding radius, shape and depth in turn. Finally, the maximum bearing force of the obtained optimal model A_3B_3C_3D_1E_3 is 14.5% higher than that of the experimental scheme.
