摘要
气垫运输工具是一种非常优良的水陆两栖运输工具。但由于其操纵性不好而使其受到很大限制。为改良其操纵性，必须对其动力学行为有较清楚的认识。
Air cushion is a very useful transportation means both by land and water. But it is restricted in its application because of its poor controllability. To improve its controllability, its dynamic behaviour must be understood and a dynamic analysis is carried out correspondingly.
