| 摘 要： | 基于势流理论研究平放圆柱形贮箱内任意充液比液体晃动问题,用Galekin方法求解该边值问题。研究液体自由晃动问题求出满足边界条件的势函数空间项,分析液体晃动频率随充液比例和半径变化的情况,并与实验结果进行了对比,吻合良好。在液体强迫晃动中从自由液面动力学方程出发消掉空间项得到势函数时间项n阶微分方程并数值求解。推导了液体作用在贮箱上的横向力,并计算不同充液比时地震加速度激励下的贮箱受力。

| Abstract: | Liquid sloshing of arbitrary proportional liquid-filled cylindrical tank is investigated based on Potential Flow Theory.The boundary value problem is solved by the Galekin method.Sloshing frequencies changed along with the liquid-filled proportions and radiuses are discussed in the free vibration,and the calculation results are compared with the experimental data,the two results have a good agreement.In addition,forced vibration is also discussed to found the time-items from the dynamic equation at the free... |
