摘要
以某混凝土重力坝非溢流坝段动力特性为背景,探讨流固耦合效应对结构自振特性的影响,运用大型有限元软件对结构自振特性进行分析计算,得出了流体对结构自振特性影响以及结构的固有频率,避免在运行过程中发生共振,造成对结构的破坏。
Take the dynamic characteristic of the non-overflow dam section of a certain concrete gravity dam as background,this paper discussed the impact of fluid-structure interaction on structures self-vibration.The impact of fluid on structures self-vibration and the natural frequency is concluded by analyzing and calculating with large-scale structural finite element software,in order to avoid resonance during operation which will cause damage to the structure.
