STUDI PENGARUH KOEFISIEN GESEK PADA KONTAK SLIDING ANTARA SILINDER DENGAN FLAT MENGGUNAKAN METODE ELEMEN HINGGA

Abstract

Contact between two surfaces occurs when mechanical components work. These contact can be categorized as static contact, sliding contact, or rolling contact. For an example, the sliding contact occurs when ring piston slide over a cylinder liner on motorcycle engine. One of the contact theory, developed by Hertz analytically, is valid only for elastic contact. In this study the formulation of Hertz is used as initial validation of the present model simulation. This project studies a case of static contact between the cylinder (indenter) and the flat plate (target surface). The displacement which is used as an input on the contact between a cylinder on a flat surface, play the important role in determining the resulted von Mises stress and contact area. In addition to the static contact, sliding contact simulation is also studied in this project with the variation of friction coefficient as input. The effect of friction coefficient on the distribution of the von Mises stress and the location of the maximum von Mises stress are studied.
