| Abstract: | A flexible connector of lifting pipes in a deep sea mining system is designed. The buttress thread (based on API standard) is used and foreign experience in connector design is referred to. With this kind of connector, the lifting pipe will only bear the axial force, free of moment. The strength of the connector is analyzed in detail, including the connecting strength of the buttress thread, the dynamic load of the pipe system, pressures inside and outside of the pipe, the lateral stress of the pipe wall and so on. Especially, a geometric model is built for 3-D contact stress analysis. The distribution graph of contact stress is presented. It is indicated that the strength of the spherical connector meets the demand. |
