Witryna8 gru 2024 · The contact pressure is Hertzian-like for \alpha < 0.01 and Gaussian-like for \alpha > 10, where the dimensionless parameter \alpha = h_ {\rm rms}/\delta is the ratio between the root-mean-square roughness amplitude and the penetration for the smooth surfaces case (Hertz contact). 1 Witryna4 maj 2015 · In non-conforming rolling contact, the contact stress is highly concentrated in the contact area. However, there are some limitations of the special contact model and stress model used for the theoretical study of the phenomenon, and this has prevented in-depth analysis of the associated friction, wear, and failure. This paper is …
