摘要
本文研究了复杂结构贮箱内液体的晃动问题.采用有限元-外推方法对一些复杂结构贮箱,特别对带有网孔隔板的球形贮箱内液体晃动特性作了详细的分析、计算和比较;在此基础上建立了充液系统的等效力学模型,并揭示了多个自由液面晃动特性与单一的自由液面晃动的不同之处.
The liquid sloshing in complex structured containers is analyzed in this paper. The FEM and the extrapolation trick are combined as a numerical method, used to calculate some liquid sloshing problems of complex structured tanks, especially, the spherical tanks with the spacers of netted-holes in detail. The results are compared with other theoretical and experimental
