Abstract

In this work, disc surfaces with two kinds of groove configurations are tested in a pad-on-disc system. The experimental results show that cutting 45° grooves on the disc surface can significantly reduce the friction noise. The main reasons are believed to be that the groove-textured surface can trap wear debris and redistribute the contact pressure and thus modify the friction shear stress. Moreover, numerical analysis is performed to simulate the experimental process and a possible mechanism is provided to explain the effect of grooved disc surface on the tribological properties and squeal generation. The groove-textured surface can significantly affect the contact pressure distribution of the pad surface and the transportation of wear debris at interface, and consequently reduce the squeal.
