【Abstract】 The landing dynamics of the carrier based helicopter was studied. Firstly, the mathematical model of random sea wave signals is presented,and the ship rocking is analyzed using super position principle and the response amplitude operator(RAO). Then,the dynamic model of helicopter fuselage is established using the Lagrange equation with dissipation energy.Also,landing dynamics of the carrier based helicopter is simulated combining the classical ship model and the carrier based helicopter dynamic model. The Runge-Kutta method is used for calculating the dynamic model,and the dynamic model is verified with Matlab.更多还原
