Design and research on carbon fiber composite material in a ship propulsion shafting
In view of the characteristics of light weight,high strength and strong vibration absorption of carbon fiber composites,the design of carbon fiber composites in the propulsion shafting of a warship was studied.Based on ACP mod-ule of Ansys Workbench,the calculation and analysis model of ship carbon fiber composite shaft section was established.Through the analysis of different lamination schemes,different lap lengths and different connection methods,the torsion and tension and compression resistance of carbon fiber composite shaft sections under different conditions are studied,and the design scheme of ship carbon fiber composite is found.Finally,the designed carbon fiber shafting is compared with the pure steel shaft,and the design and analysis flow of carbon fiber shafting is formed.The research shows that the torsion and ten-sion and compression resistance of the marine propulsion shafting can be significantly improved when the carbon fiber com-posite shaft segments are mixed,the overlapping length is 160 mm,and the laying mode is[(15°/45°/60°/90°/-60°/-45°/-15°)14].Compared with the common shafting,the carbon fiber composite shafting can be improved.The results can provide reference for the design and calculation of the propulsion system of the same type of ships in the future.
