摘要
Based on the theory of fluid-structure coupling dynamics, a smoothed particle hydrodynamic model of a two-dimensional rectangular tank was established. Dummy particles were utilized for the treatment of wall boundary in the simulation. Firstly, the effectiveness of the model was verified by comparing simulation results with experimental results. Then, the effects of rolling excitations and various liquid filling levels on impact pressure were discussed. On this basis, different baffle structures were designed, including single and combined baffles. After that, the characteristics of free liquid surface morphology and impact pressure were investigated at the resonance frequency and 30% filling rate. The results show that (1) the roll amplitude has the greatest effect on the pressure peak at the resonance frequency; (2) with the increase of filling level, the double peak characteristics of impact pressure disappear gradually; (3) the T-baffle is beneficial to reduce the level of impact load as the baffle scale is small; (4) and the double T-shaped baffle is effective in reducing impact force at the bottom of the tank. © 2024 China Ship Scientific Research Center.
