| 摘 要： | 文中论述了一种贮液圆柱壳动力特性的分析计算方法,分析了弹性壳和液体之间的相互耦合作用。假设贮液满足速度势理论,对于圆柱空壳采用有限元法计算其动能和应变能。采用这种方法,节点未知数数目远小于壳体和液体部分都采用有限元法时的节点未知数数目。

| Abstract: | In this paper,a reliable and effective method for calculating the dynamiccharacteristics of fluid-filled cylindrical tanks is developed.And the effect ofthe coupling between liquid sloshing and shell vibration is considered.Theliquid is assumed to follow the velocity potential theory,and the shell ismodeled by the finite element method.In this approach,the number of unknownsis substantially less than those in analyses where both tank wall and liouidare subdivided into finite elements. |
