Abstract

First of all, this paper establishes air cushion vehicle bottom waveform obtained by the superimposition of wave-making water surface deformation in calm water and wave waveforms in external environment. While taking advantage of the continuity equation of flow to establish air flow system, this paper establishes a more comprehensive mathematical model of 6-DOF motion control for air cushion vehicles. On this basis, we also build the beach model from the water to the land slope as well as the models of ditch and obstacle. At the same time, we have predicted the craft's dynamic trim in the process of air cushion vehicles' climbing the beach. Forecast results can better reflect the basic motion characteristics of air cushion vehicle, and simulation results can be used to further study the manoeuvrability of air cushion vehicle, debug and optimize the manoeuvrability-control system.
