Application of virtual prototyping in study of characteristics of propulsion system of hovercraft

Traditional research methods weren't appropriate to study of characteristics of hovercraft's propulsion system for structure traits of hovercraft.So a kind of method based on modern virtual prototyping to study characteristics of hovercraft's propulsion system was put forward in the paper.And modeling of ship hull of hovercraft,modeling of shafting and coupling way between hull and shafting were studied and compared.Finally,dynamic bearing force of a kind of hovercraft's propulsion shafting was analyzed using the research method presented in the paper.
