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 kinematic dynamics of shipborne helicopters after landing was studied. First of all, aiming at the random uncertainty of the sea wave signal, a mathematical model of the sea wave signal is proposed according to the wave theory. Then the statistical characteristics of the sea wave are described by using the sea wave spectrum. The irregular wave is simulated by MATLAB simulation platform and analyzed. Finally, based on the Lagrange equation, a dynamic model of the fuselage of the ship was established. The dynamic simulation of the carrier-based aircraft on the warship and the real-time solution of the dynamic model by Runge-Kutta method were carried out.
