In order to optimize the control strategy of the wing-sailed slewing hydraulic system during small angle rotation,a multi-stage wing-sail with large lift coefficient was selected,and the aerodynamic characteristic curves of the wing-sail were obtained according to the wind tunnel experimental data of the wing-sailed model.The wing-sailed slewing hydraulic system of the target ship was designed based on experimental data,and the AMESim simulation model of hydraulic system was established,the correctness of the AMESim simulation model was verified in the hydraulic experimental station.Based on the small angle rotation of ships wing-sail,the starting and braking control signals were determined,and then the optimal control strategy of starting and braking of hydraulic system was obtained.The results indicate that the hydraulic system adopts a sine control signal for starting and braking,and the system pressure fluctuation is small when the starting and braking time is 2 s to 3 s,which is conducive to the stable operation of the hydraulic system.
