| 摘 要： | 通过速度势的特征展开方法,建立垂直圆柱对波浪绕射的解析解,得到作用在柱体上的波浪力计算表达式,通过谐波增量平衡法(IHB法),计算研究弹性双柱相对位置对双柱振动响应的影响。设计了弹性双柱体模型试验,数值结果与模型试验结果较吻合,为海洋工程结构振动设计提供一种解决方法。

| Abstract: | Under the assumption of potential flow and linear wave theory,a semi-analytic method based on eigenfunction expansion is proposed to predict the hydrodynamic forces on arrays of bottom-mounted,surface-piercing circular cylinders.The in-line responses of two flexibly mounted cylinders then are solved by incremental harmonic balance(IHB) method.Experiments are then designed and performed in a wave flume to determine the accuracy of this method in regular waves. |
