摘　　要：为了解三维弹性液舱内液体晃荡情况,采用ADINA模拟不同激励频率下液舱内液体的晃荡,将所得的结果与解析解进行对比,得到不同载液率下弹性液舱内液体晃荡特点,得到液舱载液率、外界激励等参数变化对液体自由表面运动及晃荡荷载的影响。Based on ADINA, the liquid sloshing in three-dimensional elastic tanks was simulated. First, making the bulk- head stiffening, liquid sloshing of different external excitation were simulated and the results were compared with the analytical solution to verify the correctness of the model ; Then liquid sloshing in elastic tank of different filling rate were simulated to study the filling rate and external excitation influence upon the free surface displacement and sloshing impact load.
