摘　　要：基于有限体积VOF方法以及势流体有限单元优势,提出了一种火箭贮箱液体晃动等效模型参数快速而精确的数值计算方法,并用具有解析解的圆柱贮箱模型对该方法的准确性进行了全面的验证。由于该方法不受贮箱外形和内部装置的限制,可用于任意贮箱液体晃动的研究。Based on the finite volume method(VOF) and the advantage of potential fluid element, a fast and accurate numerical method for calculating the parameters of equivalent model of liquid sloshing in rocket tank is presented, the accuracy of the method is verified by a cylindrical tank model with analytic solution. Because the method is not limited by the shape and internal device of the tank, it can be used to study the liquid sloshing in any tank.
