摘    要:应用任意拉格朗日-欧拉有限元方法分析大型u形渡槽结构中流体的大幅晃动问题;针对不同的水位,研究渡槽结构在谐波激励和地震作用下的振动反应.数值分析表明,渡槽结构中水体的晃动具有明显的非线性特征,且随着水位的增高,水体晃动的非线性增强;同时存在某一水位使得水体的晃动幅度产生突变增大.

关 键 词:U形渡槽  任意拉格朗日-欧拉法  流固耦合  非线性晃动  水体晃动

Abstract:Arbitrary Lagrangian-Eulerian method is used to study large sloshing of water in large scale U-shaped aqueduct, and to discuss the vibration responses of aqueduct structure with different water levels under sinusoidal loads and earthquake action. Analysis of the data indicates that nonlinear behaviors arise from the sloshing of free surface, and become stronger with increase of the water level. Meanwhile, under a certain water level, the sloshing will increase suddenly.
Keywords:U-shaped aqueduct  arbitrary Lagrangian-Eulerian method  fluid-structure interaction  nonlinear sloshing
