摘要： 织构化滑动摩擦副表面织构的排布方式、尺寸和形状是决定其压力分布和承载力的关键因素。为改善织构化滑动摩擦副表面的润滑与承载特性，提出了一种变织构（尺寸多样的织构）结构。以球冠形织构为研究对象，建立不同排布方式的单一尺寸织构及方形排布变织构的CFD （computational fluid dynamics，计算流体力学）仿真模型，分析了排布方式不同的单一尺寸织构表面的压力分布和承载力；在此基础上，研究了半径两端小中间大（A型）、半径两端大中间小（B型）、深度两端浅中间深（C型）及深度两端深中间浅（D型）等4类方形排布变织构表面的压力分布和承载力。结果表明：方形排布的单一尺寸织构的润滑性能最强且承载力最大，随着错位角的增大，织构间的协同润滑作用减弱，承载力减小；单一尺寸织构的压力分布曲线为周期性波动曲线，由多个单织构的压力分布曲线叠加而成，而方形排布变织构因前后织构的协同润滑作用而导致其压力分布曲线的趋势线近似呈正弦或余弦规律波动；在4类方形排布变织构中，B型变织构的承载力大于A型，D型大于C型，说明两端织构的半径越大、深度越深或该类织构的占比越大，则变织构的承载力越大。由此可见，合适的变织构比单一尺寸织构更有助于提升摩擦副表面的润滑与承载性能。
Abstract: The arrangement, size and shape of the textures on the textured sliding friction pair surface are the key factors that determine the pressure distribution and bearing force. In order to improve the lubrication and bearing characteristics of the textured sliding friction pair surface, a kind of variable texture (texture with various sizes) structure was proposed. Taking the spherical crown texture as the research object, the CFD (computational fluid dynamics) simulation models of the single-size texture with different arrangements and the variable texture with square-arrangement were established, and the pressure distribution and bearing force of the single-size texture with different arrangements were analyzed; on this basis, the pressure distribution and bearing force of four types of variable textures with square-arrangement, such as small radius at both ends, large in the middle (A-type), large radius at both ends, small in the middle (B-type), shallow depth at both ends, deep in the middle (C-type), and deep depth at both ends, shallow in the middle (D-type), were studied. The results showed that the single-size texture with square-arrangement had the strongest lubrication effect and the largest bearing force; with the increase of dislocation angle, the synergistic lubrication effect between textures weakened and the bearing force of the texture decreased; the pressure distribution curve of the single-size texture was a periodic fluctuation curve, which was composed of pressure distribution curves of multiple single texture. The trend line of pressure distribution curve of the variable texture with square-arrangement was approximately fluctuating in a sine or cosine law due to the synergistic lubrication effect of the front and rear textures; among the four types of variable textures with square-arrangement, the bearing force of the B-type variable texture was lager than that of A-type, and D-type was larger than C-type, that was, the larger the radius, the deeper the depth of texture at both ends, or the larger the proportion of such texture, the bearing force of the variable texture was larger. It can be seen that the variable texture is more helpful to improve the lubrication and bearing performance of the friction pair surface than the single-size texture.
