Research on the Friction Characteristics and Structural Deformation of Textured Valve Plate Pair in High-speed and High-pressure Axial Piston Pump
摘要
Abstract
To improve the friction performance of the valve plate pair in axial piston pumps under high-speed and high-pressure conditions,triangular,square,and cylindrical surface textures are constructed on the valve plate.A one-way fluid-structure interaction simulation model of the piston pump is establishedy using ANSYS.The effects of different rotational speeds and pressures on the oil film load-carrying capacity,friction coefficient,and structural deformation are analyzed and compared between textured and non-textured valve plates under full film lubrication.Results show that,compared to non-textured valve plate pair,the textured pair exhibits increases oil film load-carrying capacity and reduced friction coefficient as speed and pressure rise.However,solid domain deformation increases.Within a broad range of high-speeds and high pressures,the triangular texture demonstrates superior comprehensive performance compared to square,cylindrical,and non-textured surface.Under high-speed and high-pressure boundary conditions,the oil film load-bearing capacity of the valve plate pair with triangular texture is increased by 22.51％compared to that of the non-textured surface;the friction coefficient is reduced by 18.24％;and the maximum deformation of the cylinder block and the valve plate increases by only 10.9％and 1.6％,respectively,compared to those of the non-textured surface,demonstrating significant performance advantages.关键词
