【摘要】 本文研究微重状态下旋转对称刚性容器中液体晃动问题。用摄动迭代法计算静止自由液面,精度较高。利用微幅晃动条件,使运动方程线性化,导出了液体晃动固有频率的计算公式。最后,对园柱形容器进行了具体计算。更多还原

【Abstract】 This paper studies sloshing characteristics of liquid in axisymmetric rigid tank. The staticliquid surface at low-gravity environments is calculated by means of perturbation and iteration method. Results possess higher accuracy. Based on the little amplitude vibration condition, the liquid dynamic equations are linearized. The calculation formula of liquid sloshing frequencies is deduced. The paper takes the calculations of cylindrical tank as examples.更多还原
