VIBRATION ANALYSIS OF UNIFORM COLUMNS WITH ARBITRARILY SHAPED CROSS SECTIONS PARTIALLY SUB MERGED IN WATER

本文研究部分潜入水中的任意形状等截面柱体的弯曲自由振动问题,应用Fourier级数匹配法,提供了一个精确计算这类柱水耦联系统振动特性的解析方法,结果可由计算机解出。本文最后取水中椭圆柱体为例,给出了一些具体的数值计算结果。

This paper studies the problem of free bending vibration of uniform columns with arbitrarily shaped cross sections partially submerged in water. A general, exact, analytical solution based on Fourier collocation method is presented to solve the dynamic characteristics of coupled vibration of columns with water. Finally, some numerical results are given for elliptical columns submerged in water.
