摘要
取船舶舷侧加筋板结构为研究对象,根据其在球鼻艏结构撞击下的变形特点,将加筋板结构离散为板材和骨材两类单独结构。运用简化解析法推导其碰撞力的表达式,再根据变形协调条件进行叠加。经过与试验结果的对比发现,该解析法计算结果与实际情况相符,精度较高。可将该公式用于对舷侧加筋板结构碰撞的初步估算。
Taken the basic stiffened plate structure as the research object,according to the deformation characteristics of the impact of bulbous bow structure,the stiffened plate structure is divided into plate and two kinds of single structure.The expression of the collision force is deduced by the simplified analytical method.Through the comparison with the experimental results,the calculation results of the analytical method are of high precision.So this formula can be used to estimate the side structure collision.
