浸水圆柱壳振动特性的有限条──边界元分析

Study on Vibration of Cylindrical Shells Submerged in Water by FS-BE Method

根据圆柱壳的结构特点 ,对浸水圆柱壳进行有限条—边界元分析。在流场的边界元分析中 ,采用了一种特殊的边界单元 ,这种边界元不仅能与结构的有限条单元协调 ,而且计算量小 ,精度高。在此基础上 ,对浸水圆柱壳的振动频率、模态以及响应作了全面分析 。

By use of finite strip and boundary element method, the vibration of cylindric al shell submerged in water has been studied. A special boundary element of wat er area is proposed in this paper, which coincide with FS of cylindrical shell well. And also, a good results with less computer resource.was achieved.
