摘要
本文利用加权残数法，求解了浸沉于半无限深理想势流中圆柱形结构的固有振动。数值算例表明，这种方法，计算量适中，试函数的选取合理；适用于工程中对水下航行体固有振动的求解。
By the use of the method of weighted residuals, resonant vibration of a cylindrical beam in asemi-infinite potential flow is investigated. A numerical example suggests that the trial function used in themethod is efficient and reasonable.
