| 复杂海况下传递对准受杆臂效应影响较大，主要体现在失准角发散程度和对准时间长短。为研究不同等级海况对杆臂效应的影响程度，本文基于分离建模的思想建立船舶六自由度模型，进而建立等效杆臂效应模型。仿真中在等效杆臂效应模型中采用速度匹配传递对准，对比分析中采用卡尔曼滤波、巴特沃斯低通滤波器补偿和计算补偿法三种方法，仿真结果表明：五级海况为进行传递对准的最高等级海况。仿真结果为实际演训、作战、执行任务等提供一定理论依据，也能为船舶安全及舰载机起降训练安全提供指导意义。 |

| Transfer alignment is greatly affected by lever arm effect in complex sea conditions, which is mainly reflected in the divergence degree of misalignment angle and the duration of alignment. In order to research the influence of different sea conditions on the lever arm effect, a ship six-degree-of-freedom model is established based on the idea of separated modeling, and an equivalent lever arm effect model is built on that basis. In simulation process, velocity matching transfer alignment is adopted in the equivalent lever arm effect model, and Kalman filter, Butterworth low-pass filter compensation and computational compensation methods are applied in comparative analysis. The simulation results show that the fifth grade sea state is the highest sea state grade for transfer alignment. The simulation results provide a theoretical basis for practical training, combat and mission execution, and also provide guidance for ship safety and the safety of carrier-based aircraft take-off and landing training. |
