摘要高速、重载工作条件下，机械结构滚滑并存界面的温度热效应变得显著，可导致系统的动力学特性、磨损特性和工作稳定性等发生根本性变化。本文通过建立滚滑并存线接触粗糙界面模型，基于界面的法向载荷由润滑油膜和粗糙体共同承担的载荷分配思想，采用Greenwood-Williamson统计模型描述粗糙表面形貌，考虑界面温度热效应的影响，建立了滚滑并存线接触粗糙界面的能量方程、油膜厚度方程和粗糙体接触压力方程，求解了界面温度场，获得了表面粗糙形貌、界面法向载荷和运动速度对热润滑油膜厚度参数和摩擦能量耗散量的影响特性，为机械结构的润滑状态预测和系统动态性能分析提供基础。

Abstract：The thermal effect of a rolling-sliding coexisting line contact rough interface becomes significant under high speed and heavily loaded working conditions to cause fundamental changes of the system’s dynamic characteristics, wear performance and stability. Here, considering thermal effect, the rolling-sliding coexisting line contact rough interface model was established based on a load sharing idea of total normal load on an interface being shared by a lubrication oil film and a rough interface. The rough surface topography was described using Greenwood-Williamson statistical model. The interface’s energy equation, oil film thickness equation and contact pressure equation were established considering the interface’s thermal effects. The interface’s tempeture field was solved. The influence characteristics of surface rough topography, interface normal load and motion velocity on thermal lubrication oil film thickness and frictional energy dissipation were derived. The results provided a foundation for mechanical structures’ lubration state prediction and the system dynamic performance analysis.
