Abstract

Rectangular containers are used for numerous liquid transports in many industrial applications. However, unwanted slosh in the container degrades safe and reliable operations. A three-dimensional nonlinear slosh model in a more clear way is presented, which benefits simulations of the nonlinear slosh dynamics. In addition, a new method is designed for suppressing the nonlinear slosh by filtering the driving commands. Comparison between the new method and a previously present method is also explored. Many simulations are conducted to analyze the sloshing dynamics and the effectiveness of the new method. Experimental results obtained from a moving rectangular container validate the dynamic effects and the effectiveness of the method.
