全垫升气垫船6自由度操纵运动建模与仿真

ue to the movement complexity of air cushion vehicle, so far the research has been focused on 4-DOF motion, but the 4-DOF motion equation is difficult to reflect the real movement characteristics of air cushion vehicle. In this paper, the forces of aerodynamic, propellers and rudders were obtained by wind tunnel experiments, the water surface deformation under air cushion was obtained on the basis of linear wave theory, the lift fan - air duct- skirt - air cushion dynamic balancing cushion system was obtained according to the flow balance principle, at last, the 4-DOF motion model was established according to Newton's momentum and moment of momentum theorem, and the results of movement simulation was obtained. The simulation results show that the motion model is rational, The motion model has been successfully applied to a certain type of steering simulator.
