摘　　要：可启闭船艏结构是一种新型的特殊水密门结构。详细介绍了船艏结构的设计特点及考虑的影响因素,通过模型试验方法确定了设计外载荷,并对船艏结构有限元模型在开启状态下的应力和变形进行了计算。根据计算结果对船艏结构进行了适当加强。经实船试验验证,可启闭船艏结构能够满足高速艇的使用要求。The structure of prow being able to open and close is a new type of structure for watertight door,with design standard not provided and design drawing not referred.The feature of prow structure and some influencing factors considered in design are presented in this paper.The external load is determined with model experiment.By the use of finite element model the stress and strain of the prow are calculated under opening condition.According to the result,the structure has been proper strengthened.The full scale test shows that the prow structure being able to open and close would satisfy the operating requirements of high-speed ships.
