| 摘 要： | 本文考虑界面摩擦力对粗糙表面接触性能的影响以及摩擦副表面间存在相对滑动时界面的局部高温对表面膜的影响,推导了考虑摩擦力后粗糙表面塑性指数的表达式,并对粗糙表面的接触性能进行了研究,研究结果表明:摩擦力的存在将影响粗糙表面的塑性变形特征。这种影响将随椭圆比的增加而增加,在研究摩擦表面变形特征时必须考虑这一影响。本文提供的修正塑性指数表达式为进行滑动接触时的接触性能分析提供了有力的工具。

| Abstract: | Considering both the effect of frictional force and the local high temperature, a new plastic index expression is proposed and the contact behaviours of rough surfaces are studied in this paper. The results show that: the frictional force has an affect on contact behaviour of rough surfaces, the effect will increase with the elliptic ratio of rough surface and must be consi dered in studying the deformation behaviour of rough surface. The revised plastic index proposed in the paper will be the helpful foundations to analyze the deformation behaviour of rough surface at sliding contact. |
