摘要
本文采用有限环单元分析罐体，对罐中液体，通过液体运动的准确解表示液动压力，应用虚功原理导出与液动压力等效的流体附加质量矩阵，将其叠加到壳体单元的质量阵中，进行罐──液体系的动力特性分析。
In this paper,the dynamic behaviour of liquid storage tanks is studied with a semi-analytical method.By using the exact solution of the fluid motion and the principle of virtual work,the attached mass matrix of the fluid is established and added to the mass matrix of the shell structure to analyze the dynamic behaviour of the stucture-fluid system.
