| 摘 要： | 本文研究了在失重状态下球形腔体内液体的晃动问题.首先分析了静液面的形状, 并用多项式构造了一类特征函数, 进而求解了球腔内液体晃动的力学特性, 并通过数字计算得到了一些晃动参数:如晃动频率、动力系数、阻尼比等.

| Abstract: | In the paper, the sloshing of liquid in a spherical tank is investigated under low-gravity conditions. After determination of the equilibrium shape of free surface of liquid, using a method concerning a kind of characteristic functions, expanded into po-lynominal expressions, the free and forced sloshing problem had been solved.The computer results for sloshing frequencies, dynamical coefficients and damping ratio had been obtained. |
