摘　　要：对舰载直升机着舰后的运动动力学进行了研究。首先针对海浪信号的随机不确定性,根据海浪波理论,提出了海浪信号的数学模型,然后利用海浪谱描述海浪的统计特性,运用MATLAB仿真平台仿真出不规则海浪并对其进行谱分析。最后基于拉格朗日方程,建立了着舰的机身动力学模型,对摇摆舰艇上的舰载机进行了动力学仿真并采用龙格库塔法对动力学模型进行实时解算。The landing dynamics of the carrier helicopter on complex deck was studied. First, the random uncertainty of sea wave signal was considered, and the mathematical model of the sea wave signals was proposed according to the wave theory. The statistic characteristics of the sea wave were described by the way of sea wave spectrum. The irregular approximate progressing waves were simulated on MATLAB simulation platform, and the spectral estimation of the sea waves was conducted. Then, the landing dynamic model of the fuselage was established based on Lagrange equation. Finally, the dynamics simulation of the carrier helicopter on the complex deck was carried out and the Runge-Kutta method was used for the real-time calculation of the dynamic model.
