摘要：The smooth particle fluid dynamics (SPH) method and Finite Element (FEM) coupling algorithm are applied to study the problem of large sloshing impact cap in rectangular tank. The simulation results are compared with the experimental results. The results show that the numerical simulation results are in good consistent with the model test results. The feasibility and effectiveness of the method are verified. The liquid storage tank is more prone to liquid sloshing and impact capping under high liquid filling rate, and when the excitation frequency is approached to the first-order sloshing frequency of the liquid, the peak value of the sloshing increases as the amplitude of the sloshing increases, and the impact pressure process exhibits significant oscillation and random characteristics.
