A　two-dimensional　sliding　model　of　double　rough　surfaces　was　established,　and　the　conditions　for　the　fixed　sliding　speeds　which　considered　adhesion　factors　in　the　process　of　contact.　The　friction　and　wear　of　sliding　processes　were　analysed　using　the　finite　element　analysis　take　into　account　elastic-plastic　material　properties　with　material　failure.　The　wear　rate　and　vibration　were　compared　and　analysed　whether　or　not　considering　adhesive　factors,　the　vibration　power　spectrum　was　obtained　based　on　FFT　arithmetic.　The　numerical　results　show　that　the　average　coefficient　of　friction　is　0.48　when　the　interfacial　shear　strength　τ=σy/√3　(where　σy　is　the　yield　strength).　In　the　case　of　considering　adhesion,　wear　rate　is　larger,　power　spectrum　low　frequency　component　is　more,　vibration　is　relatively　gentle,　the　corresponding　energy　also　is　larger.　Compared　with　experimental　results,　it　is　concluded　that　the　rationality　of　the　simulation　exists,　these　results　also　deepen　understanding　the　physical　image　of　the　friction　and　wear　processes.
