1)Asperity[英][?'sper?ti][美][?'sp?r?t?]微凸体
1.Based on the assumptions that the particle is round or hexagonal and the asperity contour is round or cosinoidal,the rubbing temperature of the particle on the asperity is studied as well as its effect on the temperature and pressure properties of the liquid.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。
2.A model was developed which used a discretiza- tion method to obtain the asperity height and deformation mode.通过ＳＴＡＲ－１型表面轮廓仪对粗糙表面实际形貌的测定，分析得到了实际表面微凸体的高度分布和曲率分布，发现微凸体的高度分布并非高斯，而曲率分布则呈随机状态。
3.The friction,friction coefficient etc of prescind from external asperity model and the single asperity model in plasticity forming were respectively researched by using finite element analysis software ADINA and Coulomb friction model and nonlocal friction model.应用大型有限元软件ADINA,采用库仑摩擦模型和非局部摩擦模型,对不考虑表面微凸的模型和单个微凸体模型在塑性成形中的摩擦力、摩擦系数等进行研究。
