Abstract
The liquid transported in thin-walled containers is widely used in many engineering applications. The elastic sidewall interacting with the liquid sloshing degrade the operation safety. Dynamic equations of the liquid-filled containers with flexible sidewalls undergoing planar motions were derived. The equations depict the dynamic interaction between the liquid sloshing and elastic sidewall. Furthermore, the frequency-estimation equation of the interaction is also described. Then, a new technique for controlling the coupled oscillations caused by the interaction is introduced. The computational simulations were performed to analyze the complicated dynamic interaction and verify the effectiveness of the control method. The theoretical findings may also benefit other types of thin-walled liquid-filled structures.
