中文摘要	Based on the assumption of the ideal fluid, the coupled dynamics equations of movement of rigid tank and nonlinear sloshing of liquid are established through H-O principle, with the modified potential function introduced to describe the moving boundary of rigid tank and fluid. Galerkin's method is used to discrete the equations. Benchmarked with some FEM and BEM results, feasibility of the present method is proved. The responses of the coupled system to the excitement by some forces are simulated. The equivalent theory is used to explain the increase of the natural frequencies.
