This paper introduces two basic problems of dynamic model and damping device in liquid sloshing. The necessity of establishing equivalent mechanical model is discussed. The formulas for calculating parameters of equivalent mechanical model are given. It is pointed out that the dynamic effect of liquid sloshing can be basically described by the first-order shaking equivalent mechanical model. The experimental method is used to determine one Akira power model parameters. Briefly introduce the damping effect of the ring baffle and the efficient semi-circular baffle. A comparison of typical experimental results with calculated results is given. A number of topics to be further studied such as nonlinear problems are proposed.
