In recent, a lot of interesting and challenging attempts have been reported to reduce sloshing loads in a tank, such as baffle, floaters and perforated panels, etc. Because the sloshing phenomena represents random and highly nonlinear behaviors, which makes the analysis extremely difficult and lead to a new level for challenging at the moment, the prediction and mitigation of sloshing impact have often been dependant on experiments and statistical analysis. In a past few decades, some numerical methods have been suggested and applied to solve the sloshing phenomena while computer performance and numerical techniques are rapidly improved. In the preset study, a series of experiments and numerical simulation are performed to understand the sloshing behavior of fluids interacting with two horizontal plates connected to springs to the top of the tank as damping system, and examine the mitigation effects of sloshing impact. For the numerical simulation, a coupled system of Smoothed Particle Hydrodynamics (SPH) for solving fluid motion and Multibody Dynamics (MBD) for dynamic movements of mechanism system has been developed. The simulation results are compared with those of experiments for validating the developed numerical system, and the mitigation effects of sloshing due to the spring-linked damping systems are discussed.
