- TITLE: FINITE ELEMENT ANALYSIS OF THE DIAMOND BURNISHING PROCESS OF HOLES IN CuAl8Fe3 ALUMINUM BRONZE
- ABSTRACT: This article presents the results obtained from finite element (FE) analysis of the diamond burnishing process of holes in sliding bearingsmade of CuAl8Fe3 aluminum bronze. For this purpose, a fully coupled 3D FE model of the studied process was developed. The model makes it possible to assess both the temperature effect and the stressed and strained state in the surface layers around the hole. It was found that in diamond burnishing the temperature athole surface pointsis characterized by a strong gradient, reaching a maximum value , after that it decreases very quickly. Based on the FE results for the equivalent plastic strain C54.284T max,A p distribution in a depth, it was found that the hardened layer has a thickness of mm75.0 . The diamond burnishing process provides an intensive compressive zone with useful hoop residual stresses in the surface layers around the hole in CuAl8Fe3 bronze sliding bearings.MPa340res max,t
