The　rubber　bush　of　the　stator　is　not　only　the　damageable　parts　of　the　opposed　biconinal　cone　screw　high-pressure　seawater　hydraulic　pump,　and　the　combining　status　between　the　stator　and　rotor　has　a　significant　impact　on　the　performance　of　the　new　type　pump,　so　the　related　research　on　above　problems　are　carried　out.　The　contact　finite　element　equation　of　the　shell　and　bush　is　established　and　the　deformation　and　stress　of　the　stator＇s　space　and　plane＇s　model　under　the　force　state　are　compared　and　analyzed　with　the　finite　element　method,　and　discuss　whether　the　plane　model　could　replace　the　space　model　on　the　finite　element　analysis　shows　that　the　deformation　and　stress　of　the　stator＇s　plane　model　and　space　model　have　much　difference,　so　the　plane　model　can＇t　replace　the　space　model　on　the　research　of　the　finite　element　analysis.
