| 摘 要： | The added mass coefficient and the water level indexformulas for the same-phase and anti-phase vibration of rectangularliquid tanks＇ bulkheads were derived based on dry mode theory.Three fluid-structure interaction numerical methods including FluidFEM and Fluid BEM were used in this case. The comparison ofnumerical and theoretical results by the present method shows thatANSYS/FluidS0 is more credible, the NASTRAN/Virtual MassMethod is more suitable for engineering calculations and results ofthe same-phase vibration by the present method is more accurate.
