摘　　要：在考虑粗糙度效应、时变效应、温升效应和润滑剂非牛顿特性的基础上,采用直接迭代法、逐排扫描法求解润滑方程组和温度控制方程,通过一定的数值计算,探讨了粗糙表面形貌参数对润滑特性的影响。Taking into account the effect of roughness, transient, thermal and characters of non-Newtonian lubricant, this paper numerically analyzes transient thermo-elastohydrodynamic lubrication problem in line contact,using the direct iteration method and a sequential column sweeping scheme, respectively to solve the pressure equations and the temperature equations. With the methods,a great number of solutions have been obtained to investigate the influence of amplitude,wavelength and phase of the cosine roughness in EHL.
