| 摘 要： | 针对液体晃动重心变化对航空航天器、载液货船等载液系统运动及姿态稳定性的影响,结合某型飞机副油箱的晃振试验,采用光滑粒子流体动力学（SPH）方法对该油箱进行了5个晃动周期的数值模拟。推导了任意时刻液体晃动重心的计算表达式,获得了晃动过程中的液体重心变化时间历程曲线,体现了周期性激励作用下液体晃动轨迹的周期性。

| Abstract: | According to the influence of movement and attitude stability for liquid-storage system,such as aerospace and aviation,liquid-storage ship and so on,numerical simulation of tank liquid sloshing with SPH method in 5 cycles were performed on the basis of a certain type aircraft auxiliary fuel tank slosh and vibration test.The calculation formulas on the center of gravity for liquid were derived.Time histories of the fuel CG transition were plotted.The CG transition curves show periodicity under periodic excitation. |
