摘要

在考虑流体黏性及表面张力作用的情况下

采用分离求解器交错迭代隐式耦合的方法建立了内嵌晃荡减振器的弹性悬臂梁做自由衰减振动或受迫振动的流固耦合物理模型

并对悬臂梁晃荡减振过程进行了瞬态数值计算; 结合计算结果与减振理论

分析了内嵌流体导致梁振动衰减的主要原因

认为悬臂梁振动过程中液体受迫晃荡受自由晃荡的影响

其相对位移滞后于梁的振动位移

液体对梁的阻碍冲量大于激励冲量。由此

提出了以振动频率与驻波频率的比值γ来表征自由晃荡

并采用数值模拟方法比较了不同γ下方形容器受迫摇晃的液体作用力

以及晃荡减振器在悬臂梁自由衰减振动中的减振性能。结果表明

γ值越大

单位质量液体的减振效果越明显。该结果可为优化晃荡减振器研究提供参考。

Abstract

Considering fluid viscosity and surface tension

the free or forced damped vibration of a flexible cantilever beam with an interior sloshing absorber is numerically modeled by an implicit coupling approach of partitioned solvers

and the transient processes of vibration reduction are simulated. According to the results

the main reason for damping of the sloshing liquid is that the impact of free sloshing on the forced sloshing results in relative displacement of liquid to lag behind the beam displacement

and then the damping impulse of liquid becomes greater than the exciting impulse. A parameter γ

the ratio of the vibration frequency to the standing wave frequency

is chosen to measure the influence of the free sloshing. Numerical simulations verify that the damping effects of the sloshing liquid increases with increasing γ.
