| 摘 要： | 采用SPH方法对棱形液舱在外加激励作用下,不同充液比工况所对应的舱内液体晃动进行了三维数值模拟,并将其与实验进行对比,两者吻合较好,同时成功地模拟出液体晃动产生的波浪翻卷和破碎,进而验证了SPH方法在求解三维液体晃动问题的准确性。分析结果表明:液舱的充液比及晃动周期对于液体的晃动特性及舱壁的压力有重要的影响,在大充液比情况下,迟滞特性所表现的双峰特征消失。

| Abstract: | With the excitation,liquid sloshing in the three-dimensional prismatic tank at different fill ratios of liquid conditions are three-dimensionally simulated by the smoothed particle hydrodynamics(SPH) method.The calculation results are in agreement with the experimental results.The welter and the fragmentation of the wave are simulated. As a result,the accuracy of SPH method in solving the problem of three-dimensional liquid sloshing is validated.Analysis results show that the fill ratio of the liquid and th... |
