Modelling and numerical simulation of magnetostrictive materials for reduction of friction

Abstract This study aims to enhance the multifunctional properties in top piston rings by adding magnetostrictive materials reduce friction between them and cylinder lining. The effect will create mechanical deformations rings, with consequent reduction. present consisted of a finite element analysis (FEA), using COMSOL Multiphysics ® software, where both amplitude deformation reduction contact forces were analysed. These variables are useful predict ability introduce vibrations that can lead friction. results showed force below 4%, amplitudes sliding plane 6.50 μ m 3.20 m, approximately, axial circumferential directions, respectively. Those promising, enhancing potential smart effects ring structures.
