| 摘 要： | 本文研究了微重环境下带有隔板的球形腔体内液体晃动动力学;利用特征函数展开法,得到了自由振动和受迫振动解;进而求出了液体振动的频率及液体晃动的等效力学模型,并给出了液体对腔壁的反力和反力矩.将数值结果和无隔板的球形贮箱内液体晃动参数作了比较,表明加隔板后有明显的防晃效果.

| Abstract: | In this paper, the sloshing of liquid in a spherical tank with spacer is investigated under low-gravity conditions. Unsing the method which concerning a kind of charateristic functions, expanded into polynominal expressions, the free and forced-sloshing problems are solved. The natural frequencies of liquid sloshing are obtained. The equivalent mechanical models of liquid sloshing are given. The moment and force of liquid acting on tank wall are derived. The numerical results are compared with the ones of spherical tank without spacer, and the advantages of spacer are shown. |
