ANALISA KONTAK MULTIPLE ASPERITY-TO-ASPERITY MENGGUNAKAN METODE ELEMEN HINGGA

Abstract

The smooth surface of mecanical component will be seem to be rough if the enlargement in micro scale is conducted.a such surface has an irregulaties in topography structure because of the machning process. When in contact asperity will have a very high deformatis as increasing stress, fricties, wear, and increased temperature. That’s way, need to research to analyze Von Mises stress due to wave ratio variation at multiple asperity contact. The contact between multiple asperity which has a wave shape, is anelyzed using Finite Element Method (FEM) using Abaqus 6-5.1. The parameter studied are the variation of wave ratios i.e: 5, 10, 20 and tension-to-pressure of 0,1 and 1. The contact location are at one-eigth of a wave length away from the peak and top of peak. The result show the wave ratio decreased, it the Von Mises stress increase.
