To　analyze　the　motion　characteristics　of　the　ink　roller,　a　model　of　ink　layer　between　the　ink　distributing　roller　and　the　ink　vibrator　is　built　up　by　using　ANSYS.　The　ink　layer　is　equivalent　to　a　thin　rubber　layer　with　low　hardness.　After　analysis,　the　force　and　deformation　on　the　contact　area　of　the　ink　distributing　roller　and　the　rotation　speed　of　two　rollers　are　extracted.　Factors,　such　as　rotation　speed,　center　distance　of　two　rollers　and　hardness　of　rubber　layer,　which　affect　the　motion　of　rollers,　are　analyzed.　Result　shows　that　the　relative　sliding　increases　with　the　rotation　speed,　and　decreases　with　the　center　distance　and　the　hardness　of　the　equivalent　rubber　layer.　Compared　with　the　simulation　results　under　the　condition　of　no　ink,　at　the　same　rotation　speed,　the　relative　sliding　with　ink　is　greater　than　without　ink.　The　experimental　results　of　the　ink　transfer　experiment　are　consistent　with　the　simulation　results.　©,　2015,　Beijing　University　of　Technology.　All　right　reserved.
