论文摘要
我们研究了作用于与带有随机表面粗糙度的弹性半空间接触的圆柱体上的名义（集合平均）接触压力$ p（x）$。接触压力为$α<0.01 $，类似于hertzian，而高斯（Gaussian）则是$α> 10 $，其中无量纲参数$α= h _ {\ rm rm rms}/δ$是根平方的粗糙度振幅与平滑表面案例的渗透率（Hertz Chack）之间的比率。
We study the nominal (ensemble averaged) contact pressure $p(x)$ acting on a cylinder squeezed in contact with an elastic half-space with random surface roughness. The contact pressure is Hertzian-like for $α< 0.01$ and Gaussian-like for $α> 10$, where the dimensionless parameter $α= h_{\rm rms}/δ$ is the ratio between the root-mean-square roughness amplitude and the penetration for the smooth surfaces case (Hertz contact).
