针对碳纤维复合材料重量轻、强度大、吸振能力强的特性，以某舰船推进轴系为研究对象，对碳纤维复合材料在推进轴系中的应用进行研究。基于Ansys Workbench的ACP模块对碳纤维复合材料进行铺层建立了碳纤维轴段计算分析模型。通过对不同铺层方案、不同搭接长度、不同连接方法进行分析，研究不同情况下的碳纤维轴段抗扭转与抗拉压能力，寻找碳纤维轴系的设计方案，最后将设计出的碳纤维轴系与纯钢轴进行对比研究，形成碳纤维轴系设计分析流程。研究表明，当碳纤维轴段选用混合连接且搭接长度为160 mm，铺层方式为[ (15°/45°/60°/90°/–60°/–45°/–15°)14]时，能显著提高此推进轴系的抗扭转和抗拉压能力，碳纤维轴系较于普通纯钢轴轴系自重轻，有较好减振能力。所得结果可为后续同类型推进系统的设计与计算校核提供参考。
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 module 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 tension and compression resistance of the marine propulsion shafting can be significantly improved when the carbon fiber composite 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.
