摘　　要：[目的]为分析吊舱推进器在直航工况和小舵角工况这2种常用工况下的载荷情况,[方法]利用ANSYS软件分析某大型吊舱推进器在这2种常用工况下的结构强度,通过采用水动力计算结果,对吊舱推进器实际工作中所受载荷进行模拟,并将水动力分析结果作为输入,进行吊舱结构的仿真分析。[结果]将吊舱推进器进行部位划分,研究不同部位及关键零部件的结构强度,通过分析结果验证吊舱推进器结构设计的安全性。[结论]常规航行状态下吊舱推进器的结构安全可靠,螺栓连接部位是应力集中的主要区域,对结构安全有较大影响;吊舱推进器在不同工作情况下受载情况有所变化,但最大应力远小于强度极限。[Purpose]To analyze the load of pod propeller under two common working conditions,direct sailing condition and small rudder angle condition,[Method]ANSYS software is used to analyze the structural strength of a large pod propeller in these two common working conditions.The load of the pod propeller in actual work is simulated by the hydrodynamic calculation results.The hydrodynamic analysis results are used as input to carry out the simulation analysis of the pod structure.[Result]The structure strength of different parts and key components is studied,and the safety of the structure design of the pod propeller is verified by the analysis results.[Conclusion]The structure of the pod propeller is safe and reliable under normal sailing conditions,and the bolt joint is the main area of stress concentration,which has a great influence on the safety of the structure.The load of the pod propeller varies under different working conditions,but the maximum stress is far less than the strength limit.
