摘要

研究结构有限元耦合流体边界元算法(FE-BE算法)中结构湿表面的网格尺度划分原则具有十分重要的意义。以有限长加肋圆柱壳为研究对象,采用波数谱分析方法分离出结构主振型分量(携带能量最多的振动模式)。根据分析结果提出FE-BE算法中结构湿表面的网格尺度划分原则,并采用FE-BE算法验证了该原则的有效性。

Abstract

Investigating the principle to select element size of structural wet surface in the FE-BE algorithm has a great significance.The structural bending wavelength of the main vibration mode of a finite length ring stiffened cylinder was computed with the wave number spectrum method to provide some principle for selection of element size of a structural wet surface.Numerical computation showed the effectiveness of the principle.
