摘　　要：物体的表面结构形态在有些场合下对润滑状况有重要的影响作用。本文研究了考虑表面粗糙度的点接触问题的特点，建立了点接触的分析模型和接触物体表面的横向波形数学模型，应用多网格重积分方法求解了在给定条件下其与时间相关的弹流动压性能的解。主要分析了表面横向波形的点接触的润滑性能，揭示了油膜压力、油膜厚度在油膜接触区上随参数变化的特征和规律。The surface roughness has a considerable impact on the success of the lubrication conditions on some occasions. The model of point contact and mathematical model of surface transverse waviness are described on the basis of the study on the characteristics of point contact with regard to surface roughness. And time-dependent solutions are obtained employing a numerical method. The elastohydrodynamic lubrication behaviors of surface transverse waviness are analyzed in pure rolling conditions, and the characteristics of film pressure and film depth varying with parameters in contact area are revealed.
