| 摘 要： | 利用Lagrange方程求解波浪作用下的铰接多浮体结构运动响应.基于二维微幅波理论,将流场分成若干子区域,在每个子区域内将速度势用特征函数展开,在各区域边界上进行速度势及水平速度的匹配并结合运动方程耦合求解速度势中的系数及结构响应值.计算与实验结果的比较表明,所采用的计算方法是合理的,可以为研究波浪与铰接多浮体相互作用作为参考.

| Abstract: | The mass matrix and stiffness matrix were calculated by Lagrange equation.Based on two-dimensional small amplitude wave theory, the fluid field is divided into several regions, the velocity potential in each region is expanded by eigenfunctions.By satisfying continuity of velocity potential and level velocity on the interfaces,and coupling with the equation of motion,a set of linear algebraic equations can be obtained to determine the unknown coefficients and responses.It shows that the method applied in th... |
