高冰级吊舱推进系统在破冰突变载荷下的运行稳定性分析OA

Aiming at the operational stability of high-ice-class pod propulsion system under sudden changing of ice-breaking loads,this paper takes the pod propulsion system of an ARC7-class polar icebreaker as an example to carry out calculation of ship ice resistance and analysis of the ice load torque excitation model.A simulation model of pod electric propulsion system including the motion state of the ship is established based on Matlab/Simulink.The operational stability of the propulsion system is simulated and analyzed for the sudden change of ice-breaking load under continuous thick ice-breaking condition.The simulation results show that stable output of the power of the pod propulsion system can be achieved by adopting the power control mode,ensuring the stability of ship power grid.The results can provide a reference for the design and performance analysis of high-ice-class pod propulsion system.
