摘要
本文对固体和液体的耦联振动进行了非线性分析,尤其考虑了非线性表面波影响及液面变化所引起的边界变化。文中对流体取边界元形式,对固体取有限元形式。在时域内取差分格式,最后附有以水坝为例的电算实例。
In this paper, the solid-fluid coupling vibration has been studied especially considering the boundary changes caused by the influence of earthquake wave and the changing of fluid surface, for fluid the boundary discrete form is taken and for solid finite element discrete form is taken. In time domain the difference,method is used.In the end of this paper an example of water-dam system has been solved by means of this method. The calculation is implemented on a microcomputer.
