摘要

当斜盘轴向柱塞泵处于高压工况时,其配流盘会产生翘曲变形。基于弹性流体动力润滑理论,建立斜盘轴向柱塞泵配流副流固耦合模型,求解配流副润滑控制方程,分析了斜盘轴向柱塞泵缸体转速、缸体倾角、液压油黏度、配流副油膜厚度、配流副密封带宽度等工况与结构参数对其配流盘发生翘曲变形的影响。研究显示:斜盘轴向柱塞泵配流盘变形云图以腰形槽中心连线为轴线呈现一定的对称分布;配流盘高压侧外密封带区域变形最大,配流盘低压侧外密封带区域变形最小;在相同工况下,配流盘的材料与结构影响配流副油膜厚度与形状。
        When a swash plate axial piston pump in high-pressure conditions, its valve plate will have warping deformation. Based on the theory of elastic fluid dynamic lubrication, a fluid-solid coupling model of swash plate axial piston pump is established to help solve control equations of the lubrication about port plate pair. We also analyze the effects of operation condition and structural parameters including cylinder speed, cylinder angle, fluid viscosity, oil film thickness and seal band width on the valve plate. The research results show that the deformation cloud chart of valve plate with axial piston pump is symmetrical with the axis line of the waist groove as the axis. The deformation of outer seal zone in the high-pressure side of valve plate is the largest and that in the low-pressure side of valve plate is the least. Under the same conditions, the material and structure of valve plate affect the thickness and shape of oil film.
