摘要
本文对工程中常见的轴对称结构与周期旋转对称(Cn对称)结构的的耦合构系,分别采用轴对称单元与一般有限单元进行离散化,进而分别采用付氏级数展开技术及部分对称结构分析方法进行两个子结构的分析,以充分利用它们各自的对称性质,通过交界面上点的位移协调条件,推出了连接点上两种不同形式广义位移间的转换关系,由此将两个子结构耦合在一起。本算法对该类构系的耦合分析将有计算速度、精度方面的高效益。
In this paper,a new meth9d for the coupling vibration and static analysis of axisymmetric structure and rotationally periodic structure is presented. In order to make full use of all the symmetry properties of coupling structural system, the method combines the use of axisymmetric elements and common finite elements, and combines the use of Fourier series expansion technique and the method of partially symmetric structure analysis, leads to a very economical numerical calculation of this kind of structural system.
