文章引入颗粒形态和表面粗糙度的影响,结合雷诺方程、粘温方程、颗粒和微凸体变形及能量方程等建立了颗粒和微凸体接触时的摩擦模型;探讨了颗粒形状分别为圆形和六边形,微凸体轮廓分别为余弦和圆弧时,颗粒和摩擦副的接触温度及其对流体的温度、压力分布的影响;研究结果表明,圆形颗粒的承载量比六边形颗粒的承载量大,与微凸体的接触温度也较大,而存在圆形颗粒的流体摩擦力以及总摩擦力较小。 In this paper, the influence of particle morphology and surface roughness is introduced. The friction model of particle and asperity contact is established by combining Reynolds equation, viscosity-temperature equation, deformation of particles and asperities and energy equation. And the hexagonal and asperoid contours are cosine and arc respectively, the contact temperature between the particles and the friction pair and its influence on the temperature and pressure distribution of the fluid. The results show that the loading of the circular particles is larger than the hexagonal The bearing capacity of the particles is large, the contact temperature with the microprotrusions is also larger, and the fluid friction with the round particles and the total friction are smaller.
