有限要素法を利用したゴム凝着摩擦の簡易予測法

抄録

In this study, we proposed a simple prediction method of adhesion friction between rough rubber surface and smooth hard surface by combining Persson’s contact theory, the basic friction test and finite element method. In addition, the validity of the proposed method was verified by comparison with actual test results. As a result, the load dependence of friction coefficient can be rationally expressed by the proposed method, and it is found that the order of the friction coefficient is the same as the test result. Furthermore, the friction test of the grooved rubber was reproduced by the finite element analysis as prediction of the frictional force in an arbitrary shape, and the prediction accuracy of the proposed method was confirmed.
